Linux/DRA726: Early boot - late attach on DRA726

Michel Catudal2

Part Number: DRA726
Other Parts Discussed in Thread: DRA722, , TPS65090

Tool/software: Linux

I need to connect early with the Cortex M4 on IPU1, we have 5 CAN ports to handle and need a wake up on CAN with one of them. Right now it takes around 11 seconds for the wakeup to be recognized which is about the time that it takes to get to the M4 code.

I don't have quite enough information to fully understand how to implement the Linux portion of things.

I do not see any good information on how to load the module when booting in Falcon mode.

I was looking thru the

processors.wiki.ti.com/.../Early_Boot_and_Late_Attach

There is a problem with the info

   Device Drivers --->
     Remoteproc Drivers --->
       <M> OMAP remoteproc support
       [*]   OMAP remoteproc support for IPU
       [*]     Attach to already-running IPU2 (no reset/load/start)
       [*]   OMAP remoteproc support for DSP
       [*]   OMAP remoteproc support for IPU1 (DRA7xx only)
       [ ]     Attach to already-running IPU1 (no reset/load/start)
       [*]   OMAP remoteproc support for DSP2 (DRA7xx only)

Actual possible setting in the kernel

   Device Drivers --->
     Remoteproc Drivers --->
       <M> OMAP remoteproc support
       [*]   OMAP remoteproc watchdog timer
       [*]     Attach to already-running IPU2 (no reset/load/start)
       < >   STE-Modem remoteproc support
       < >   TI PRUSS remoteproc support

That is with kernel 4.4.45 coming with the TI 3.02 automotive SDK

The memory carveaout in the dra7xx code in u-boot and the kernel is outside of the memory for our board

Here is the content of my portion of the device tree in the kernel, does it look good?

1M seems a little big, how much does it actually need?

/*
* Memory reserved for IOMMU table carveout 0xa0000000 for length 0x100000
* Page Table Address for IPU1   0xa0000000
*/

&reserved_mem {
    latea_pagetbl: late_pgtbl@a0000000 {
                reg = <0x0 0xa0000000 0x0 0x100000>;
        no-map;
        status = "okay";
    };
};

&ipu1 {
    ti,late-attach;
    ti,no-idle-on-init;
    ti,no-reset-on-init;
};

Pavel,

Here is a log, it looks like the M4 is reset while it should not be.

Do you see anything wrong with my settings? Tomorrow I can try a simple firmware to see if it would do the same.

Perhaps the fact that the configuration doesn't have the options as in the documentation is the problem. If that is the case, how to fix that? What is the alternative to make sure that the M4 is not reset since the code is supposed to be loaded allready?

I changed the settings to match the one in the evm except that I marked a portion of memory as reserved so the Linux kernel would not wipe it out.

&reserved_mem {
   latea_pagetbl: late_pgtbl@bfc00000 {
       reg = <0x0 0xbfc00000 0x0 0x100000>;
       no-map;
       status = "okay";
   };
};

&reserved_mem {
   latea_for_ipu1: latea_for_ipu1@a0000000 {
       reg = <0x0 0xa0000000 0x0 0x1000000>;
       no-map;
       status = "okay";
   };
};

in my include file I have

/* Define the address to which the IPU1 binary is
* loaded from persistent storage
*/
#define IPU1_LOAD_ADDR (0xa0000000)

in spl.c I only have IPU1 as listed to be loaded.

Hi Michel,

To satisfy the startup time requirements of specific use cases, one may need the boot loader to boot a remote core before booting the A15 with the linux kernel. The kernel then attaches to the already booted remote core for further communication. We refer to this feature as the "Early Boot - Late Attach" functionality. The "Early Boot" functionality is provided by the boot loader. The "Late Attach" functionality is a feature of the Linux Kernel.

From what I understand you have issues in "Early Boot" in boot loader, is that correct? Please provide me the exact steps of how you configure and re-build u-boot for "early boot" functionality enabled.

Note also that U-Boot has only been updated to load remotecore binaries from the boot partition of the SD card or eMMC. If you desire to load remotecore binaries from other media (e.g. QSPI), the code to load the binaries needs to be added to U-Boot.

See also if the below pointers will be in help:

I am using the u-boot and kernel from the automotive SDK 3.02 with appropriated changes in the devicetree to support our board and LCD as well as patches to get the micro SD recognized correctly.

After it was proven to work flawlessly in booting from QSPI I added support for

I copied the late attach part from the dra7xx into my ACTIA board directory. In my u-boot the board definitions are not in the TI directory.

There were enough differences between the automotive EVM and our board that I could not use the EVM stuff as is.

I tried though to stay as close as possible to the way it is done in the EVM code and online documentation. What puzzled me is the configuration that is pointed to for the kernel doesn't match what can be done. I recall seeing it when working with SDK 2 but not this one.

I followed the documentation that you pointed to very closely. I haven't looked at changing the place where it reads the IPU1 code from yet. I wanted to test it with what is supported first. Too many changes at once makes debugging more difficult.

It doesn't appear to have any problem loading the code, how do I know if it is running right after loading? In the log I posted it looks like the core is reset anyway despite the entries in the devicetree. I don't see evidence in the log that it is running prior to that.

I don't know if the problem is with Michael's code or the early boot. I probably need to replace his code with the small example from TI first.

I have this in spl.c

#ifdef CONFIG_LATE_ATTACH
    u32 cores_to_boot[] = { IPU1 };
#endif

For the device tree I imported code from one of the evm dts files 

/*
 * Memory reserved for IOMMU table carveout 0xbfc00000 for length 0x100000
 * Page Table Address for IPU1   0xbfc00000

        no-map;
        status = "okay";
    };
};

    latea_for_ipu1: latea_for_ipu1@a0000000 {
        reg = <0x0 0xa0000000 0x0 0x1000000>;
        no-map;
        status = "okay";
    };
};

    ti,no-reset-on-init;

&timer7 {
    ti,late-attach;
    ti,no-idle-on-init;
    ti,no-reset-on-init;

};

&mmu_ipu1{
    ti,late-attach;
    ti,no-idle-on-init;
    ti,no-reset-on-init;
};

The DDR goes from 0x80000000 to 0xBFFFFFFF, we only have 1G of RAM


Does it matter in Linux if the reserved blocks are in misc places (meaning not in the same area)?

That is with kernel 4.4.45 coming with the TI 3.02 automotive SDK

This wiki page is for old GLSDK. You can use debug hints at the end of that wiki, but linux kernel info is obsolete.

omap2plus_defconfig was replaced with multi_v7_defconfig from PSDKLA 3.0 onwards, see the below wiki:

And in PSDKLA 3.2 there is no need to change the linux kernel through menuconfig, late attach is configured through device tree files. See the wiki pages I have provided in my previous post.

Please try these things and let me know if you have more questions on this issue.

DSP1 is not used in linux devicetree, I have it disabled. We do not need the DSP for the current customer

I am able to load with no problem but the IPU1 code crashes when Linux takes over

Here is what I sent to Nicolas.

cma doesn't seem to be available for the core until 9.742975 seconds into the boot.
and IPU1 is powered up which would be contrary to what is stipulated in the device tree

Shouldn't the system not try to load IPU1 again?

Michel,

Reading you posts, it is still unclear to me whether you enable this feature in u-boot. In file u-boot/configs/dra7xx_evm_defconfig.h, change CONFIG_LATE_ATTACH to y, then rebuild and load new SLP/u-boot

See also below file:
u-boot/doc/README.earlyboot

Regards,
Pavel

Pavel,

I do not know why it is not clear, the fact that it says in the log that the ipu1 code was loaded during spl should have made that obvious.

Michel,

"Early boot" is enabled and handled by SPL/u-boot, while "late attach" is enabled and handled by linux kernel. To isolate the root cause, I want to clear the "early boot" in u-boot first.

To enable "early boot" you should place the re-built SPL/u-boot and dra7-ipu1-fw.xem4 file in FAT partition of MMC/SD card or a specified eMMC partitions. "Early boot" in QSPI is not enabled by default.

As a first step can you try "early boot" in MMC/SD mode or eMMC mode (not QSPI mode), and check how it goes there?

To trace the load process, please enable debug prints of the following files:

u-boot/common/elf_remoteproc.c
u-boot/common/spl/spl.c
u-boot/board/ti/dra7xx/lateattach.c

Enable debug for both SD/eMMC mode and QSPI mode and compare the flow.

An easy way to verify that early boot is working is by stopping the A15 execution at the U-Boot prompt and connecting to the remotecore via a JTAG. Are you able to connect to IPU1 at u-boot stage?

Regards,
Pavel

Pavel,

It looks like u-boot loads it correctly, I will switch to Micro SD boot to start with to see.

Question on IPU2, what is IPU2 used for? I didn't take it out because I wasn't sure if it was used by weston.

If it is not used then I will take it out. Our board for the current customer has a fairly limited number of device populated, we don't play any movies, there is no sound or ethernet.

I use a bestbuy usb to ethernet device for my tests so I can ssh to the board.

Pavel,

With the micro SD boot the M4 code recovers, I still see some crashes

I still have the debug enable for splash so I took most of it out of this log

Some additional information:
I modified the project for the M4 code (built in CCS7) and was able to get Linux to boot without the crash that Michel described above. There are two lines in the project's app.cfg file:
xdc.useModule('ti.ipc.ipcmgr.IpcMgr');
var Resource = xdc.useModule('ti.ipc.remoteproc.Resource');

If both of those lines are commented out, there is no crash on startup. If either or those lines are included, we get the above-described crash.

Any ideas?

With the micro SD boot the M4 code recovers, I still see some crashes

Let we first fix "early boot late attach" for SD boot (as this is officially tested and supported), then we can switch to QSPI boot.

Have you made any changes in dra7-ipu1-fw.xem4 file or you are using the default one?

From this log it seems to me that the system is trying to load dra7-ipu1-fw.xem4 file again from the rootfs/lib/firmware/dra7-ipu1-fw.xem4, which is not correct, as this file is already loaded from SPL. Please double check that you have updated your DTS file with 3 late attach attributes for ipu1, mmu, timers. Remove also the dra7-ipu1-fw.xem4 file from rootfs/lib/firmware/ folder and check how it goes.

Please also enable debug messages in below files (dev_dbg, dev_info) and check how to flow goes.

drivers/remoteproc/omap_remoteproc.c

The firmware was still on /lib/firmware so we removed it. I will apply the patch to see if we get better results.

I do have the correct settings in the device tree as explained in the documentation

The firmware is custom, it has our CAN drivers for 5 CAN ports and has one interrupt pin to announce a CAN message and one output for a horn.

Without the early boot late attach it takes 20-30 seconds to start the horn which is problematic if you are trying to tell a boat driver that there is likely to be a crash.

When I take it out there is no crash but i get a message saying that it was not possible to load the firmware for IPU1

The communication between that firmware and the Linux library was working when loaded from Linux but it doesn't work when loaded from u-boot.

From the log it looks like it is loaded without any problem.

Michel,

I went through the whole thread. It looks like you have done the changes correctly. I will list the things once again so that we are in sync.

1. Enabled early boot in u-boot through the KConfig. I assume you copied the required changes into your board directory.
2. Customize the cores_to_boot array to IPU1.
3. Reserved memory for the late attach pagetable in device tree (latea_pagetbl).
4. Reserved memory for the temporary load location used by u-boot. (latea_for_ipu1)-> This is not necessary. This memory can be used by Linux once the MLO is done loading IPU1.

On the kernel side, you seem to have the device tree atrributes setup. You also need to have the firmware present in /lib/firmware otherwise Linux cannot setup communication with the remotecore.

You seem to have the remotecore loaded as well but facing issues with the core crashing when Linux comes up. This could be due to some peripherals used on the M4 being reset when Linux kernel is booting. If you can identify these peripherals e.g. CAN, you can remove these from the device tree or set appropriate flags to prevent M4 crash.

I would suggest trying with one of the IPC examples (messageq_single or ipumm(dra7-ipu2-fw.xem4) ) as a test before trying late attach with your binary.

regards,
Venkat

IPU1 code crashes if any GPIO are accessed. I checked and none of those GPIO is accessed in Linux.

We have a led that is handled by the M4 as well as several ones to access the microchip CAN devices

Just toggling one LED, If I just have the internal CAN everything works fine but as soon as I use one GPIO IPU1 code crashes.

None of the GPIO used by the Cortex M4 are listed in the device tree

Michel,

Linux is most likely turning the GPIO clock as no one is using the
GPIO from its view point. I tried to replicate your setup. I turned on
GPIO2 in u-boot and checked whether the GPIO2 instance is on when we
reach kernel prompt.

In, u-boot

/* Enable GPIO2 by writing to GPIO2_CLK_CTRL */
__raw_writel(0x1, 0x4A009760);
/* set one of the gpio2 pins to output */
__raw_writel(0xFFFFFFFE, 0x48055134);

I assume you are doing something similar in either IPU1 code or in lateattach.c:ipu1_config_peripherals() before trying to access the GPIO's.

On kernel prompt,

root@venkat-evm:~# omapconf read 0x4a009760
00030000

You can see the GPIO2 instance is turned off. I could keep the GPIO
clock on in two ways.

1. Add below attributes to the GPIO node in device tree. This is only
necessary if the GPIO2 pins are also being accessed from kernel.

&gpio2 {
ti,no-idle;
ti,no-idle-on-init;
ti,no-reset-on-init;
};

2. Delete the GPIO node from the device tree.

/delete-node/ &gpio2;

In both cases, the GPIO2 instance remains on.

root@venkat-evm:~# omapconf read 0x4a009760
00020001
root@venkat-evm:~# omapconf read 0x48055134
FFFFFFFE

You can adapt these steps to your hardware configuration.

regards,
Venkat

Venkat,

We got the early boot late attach working now, buzzer starts in less than a seconds so that is better than 30 secs which was a problem when you want to wanted to warn someone about to hit you with his boat.

I do have a big issue with having the firmware in the fat partition. I need to look to get it to load from ext4 from /lib/firmware instead so I would not have to copy it to the FAT partition. It can be problematic for field updates. Any idea on that?

We use the rpm manager to make updates. If it was on Redhat I could change the spec file to deal with that easily, I am not exactly sure how I would do that with yocto.
