Part Number: 66AK2E05

Tool/software: Linux

Hello, All,

My customer has a problem with Linux SDK at 66AK2E05. They said they have their own PCB design (not clone of our EVM). Please advise they they shall to check. The customer will join us at this topic with details.

Best regards,

Dmitry

    Dmitry,

    We need more information than Linux SDK doesn`t work to be able to help the customer. Have they checked that the SOC is powering up ? Can they connect an emulator and run a GEL to initialize the clocks and external memory. Have they run diagnostics or memory tests to see if the DDR and flash memory read-write tests pass on the board. These are the kind of tests, we run to bring up a board even before testing if the Linux SDK works on the SOC/platform.

    At the moment, with the information you have provided, we are unable to even assess if this is a hardware or a software issue so we will wait for the customer to provide these details before try to help with Linux bring up.

    Regards,
    Rahul

    Hi, to All!

    I will try to describe our problems.

    We have a custom board. DDR3 memory working fine. I have done all related DDR3 modification in u-boot and mtest don't show any errors.

    We have 1GbE that is connected to the Marvell 88E1111 PHY with mdio address is 1. I have done related modification in u-boot source and kernel device tree files. In u-boot ethernet working fine. I can boot firmware, dtb, kernel from network and start booting system with rootfs mounted over NFS.  Below You can see full boot messages. It is not the latest, but on all of them there is an error that I marked bold.

    I will try to disable all of ethernet interfaces except 1, but have no result. If you need additional information, I will provide it.

    We have boot linux to command line froim USB with ubifs, but ehrenet not working and any command to 1GbE (ex: ifconfig eth0 up) generate kernel dump.

    I work with latest PSP version (and previous too):

    ti-processor-sdk-linux-k2e-evm-03.03.00.04

    At a time I try to work with:

    ti-processor-sdk-linux-k2e-evm-03.01.00.06

    but have a pause in my work.

    Here my bootlog:

    Hi, Vladimir,

    What method of boot do you use? From the logs, it seems to me that you are booting from net, i.e. boot=net in u-boot env variables. Is that correct? If that is the way you boot, you seem to miss getting name_fw_rd. I only see the tftp for skern.bin, dtb, and kernel zImage.

    => pri boot
    boot=net
    => pri bootcmd
    bootcmd=run init_${boot} get_mon_${boot} run_mon init_fw_rd_${boot} get_fdt_${boot} get_kern_${boot} run_kern
    => pri init_fw_rd_net
    init_fw_rd_net=dhcp ${rdaddr} ${tftp_root}/${name_fw_rd}; run set_rd_spec
    => pri name_fw_rd
    name_fw_rd=k2-fw-initrd.cpio.gz


    Was there an upgrade of the u-boot from other release, like MCSDK? For nay u-boot upgrade, please issue "env default -f -a" to reset u-boot environment variables. They are not compatible from release to release.

    Hi, Rex!

    Thank you for your answer and attention! Yes, I try to boot from network. 
    I'm sorry for pure boot messages formatting. It is not clearly to see that I use firmware cpio.gz archive from ${PSDK}//board-support/prebuilt-images.

    In the above boot messages you can see:

    TFTP from server 192.168.0.102; our IP address is 192.168.0.241

    Filename './k2-fw-initrd.cpio.gz'.

    Load address: 0x88080000

    It is correct or not?

    We will try to clear all u-boot env settings and set it again from new PSDK.

    Hi, Vladimir,

    Ok. I see it. It usually is loaded before dtb and kernel, but yours is after them. That's why I missed it. Your skern.bin is loaded to 0x0c1f0000, but u-boot has version 2017.07. It seems to me that not only you had u-boot environment from a much older version, but you are not using u-boot from 3.3.0.4 either. Is there any reason you need to use uboot 2017.07? If you can use the u-boot from the same procSDK release that will be easier because it was tested with kernel in the same release. Try resetting u-boot environment variable to see if it helps.

    Another thing puzzles me is why the fw-initrd is loaded after the kernel. Is the bootcmd modified and different from the release package?

    Hi, Rex!
    u-boot from release 3.3.0.4 procSDK was my start point. But I has an errors while using it and after that I switch out on 2017 the latest version. I compared two versions and they are very similar.
    I suppose that order of firmware loading is not the matter, because we load fw into the fixed memory address and other components too.
    Rex, I need some time to switch on PSDK release version of u-boot.
    Thank you.

    Hi Rex and Rahul!

    Thank you for your inputs. Let me give you some overview of our project dedicated to 66AK2E05.

    We produced 2 identical engineering samples of the 66AK2E05 board. The schematic is based on the evaluation board but has some modifications. The major ones are that we didn’t put nand flash, replaced the Ethernet PHY chip, altered clock frequency.

    Vladimir Karakozov (team 1) works with the board 1 and other person (team 2) works with the board 2. I act as PM for this project.

    Each team goes its way trying to bring board up. Team 1 tries to boot kernel from net. Team 2 do the same from USB flash. Both teams didn’t succeeded yet.

    Vladimir gave you an overview of his team activity.

    Here are some details about team 2 workflow. They took the latest SDK 4 dated 07/2017 to run uboot, kernel, etc. They loaded initramfs, kernel, dtb (with minor modifications related to memory) from USB. The boot log is attached.

    Here are my questions:

    1. As you can see in 8.806332 time stamp the device says it doesn’t use netcp. What could be the reasons for such a message?
    2. Could you assist us in making minimal dts configuration essential for running netcp?
    3. Is it worth of sending you our schematic to clarify the matter?

    Hi, Dmitry,

    There isn't anything wrong with that message at 8.806332. The netcp is running after that message. The logs from8.822 through 8.93 show netcp is loading PA firmware. Please see snippets of TI logs from ProcSDK 3.3.0.4 as below. I noticed the firmware version is different. I am not sure if there is any implication of it.

    Hi Rex, thank you for your suggestion. Team 2 have advanced a little with the board bringup. Now the phys are detected and they are assigned with mac addresses. But when we try to send something we get the error:

    netcp-1.0 2620110.netcp: could not allocate cmd tx packet

    What could be the reasons for this sort of behaviour? Our idea it could be related to PA or PA2 but we are not sure if they are in charge here.

    Hi Rex, today we've got some new ideas and new questions.

    After examining datasheets and source code we consider the main problem is related to the DMA for PA.

    As we boot the kernel with mem_lpae=0, can it be the reason for the problem?

    Should we enable the lpae if we got 1GB of DDR3 only?

    Please loot at the corresponding log file with our comments marked bold.

    Hi, Dmitry,

    That's interesting observation. In the beginning I thought lpae=0 only matters to the memory mapping. Since you mentioned it, I checked the K2E memory map, and found mem_lpae setting only applies to K2H/K which maps (lpae=1) or not to map (lpae=0) 0x8000 0000 to 0x08 0000 0000, and the first 2GB space starting at 0x08 0000 0000 is IO coherent. For K2E, it needs to be 1. Please see memory map in the data sheet, DDR3 can't be accessed at 0x8000 0000, but only 0x08 0000 0000. 1GB should be ok because u-boot reads the SPD to get the DDR3 size

    if (lpae) {
    ddr3a_size = ddr3_get_size();
    if ((ddr3a_size != 8) && (ddr3a_size != 4))
    ddr3a_size = 0;
    }

    int ddr3_get_size(void)
    {
    ddr3_spd_eeprom_t spd_params;

    if (ddr3_read_spd(&spd_params))
    return 0;

    return ddr3_get_size_in_mb(&spd_params) / 1024;
    }

    Hi Rex, thank you for your suggestion. We tried to boot the kernel with mem_lpae=1 but things got worse. There’s no any message after “starting kernel" from uboot.

    Our current configuration doesn't differ much from default one from SDK4. We altered only `k2e-evm-cmem.dtsi` file to fit  CMEM block size our 1GB of RAM:
     
    reserved-memory {
        cmem_block_mem_0: cmem_block_mem@830000000 {
    reg = <0x00000008 0x30000000 0x00000000 0x18000000>; before
    reg = <0x00000008 0x30000000 0x00000000 0x10000000>; after
    };
    }; 
     
    cmem {
        cmem_block_0: cmem_block@0 {
    cmem-buf-pools = <1 0x00000000 0x18000000>; before
    cmem-buf-pools = <1 0x00000000 0x10000000>; after
    };
    }; 
     
    Is it enough to fit 1GB of RAM or should we change something else?
     
    We’ve got the memory map as follows:
     
    8 0000 0000 +------------------
    8 0200 0000 | zImage
    8 0700 0000 | skern-k2e.bin
    8 0800 0000 | keystone-k2e-evm.dtb
    8 0808 0000 | uRamdisk ~3Mb (dsp firmware included)
    …
    8 1F80 0000 | CMA pool
    8 2000 0000 | MPM pool
    8 3000 0000 | CMEM block
    8 4000 0000 +------------------ 
     
    Should we add mem_reserve variable in Uboot?
     
    Our idea is that Uboot configures the memory as one bank equal to 2GB and hence we should reserve the upper 1GB of this bank to have 1GB of physical DDR memory mapped.

    Our Uboot commands to boot from USB are as follows:
    ==> env set mem_lpae 1
    ==> env set mem_reserve 1024M
    ==> usb start
    ==> fatload usb 0:1 0x87000000 skern-k2e.bin
    ==> fatload usb 0:1 0x88000000 keystone-k2e-evm.dtb
    ==> fatload usb 0:1 0x88080000 uRamdisk
    ==> fatload usb 0:1 0x82000000 zImage
    ==> mon_install 0x87000000
    ==> setenv bootargs console=ttyS0,115200n8
    ==> bootz 0x82000000 0x88080000 0x88000000

    Hi Rex, is there any chance to draw attention of some guru to our problem? We really lack TI's support on the subject and go around in circles without any significant result...

    Hi, Dmitry,

    It is very hard for us on the customized environment. It seems to me that you set up is similar to ramfs boot which loads filesystem to the RAM. The boot cmd is

    bootcmd=run init_${boot}; run get_mon_${boot} run_mon; run get_kern_${boot}; run init_fw_rd_${boot}; run get_fdt_${boot}; run run_kern

    I suggest you follow TI's uboot env setup using boot=ramfs. Instead of hdcp files as TI's setup, you can modify using load from usb. That is fine.

    The kernel in TI's SDK takes roughly 512MB space. U-boot loading area doesn't reflect what the memory map looks like after kernel runs. So, space for dtb and skern don't exist after kernel started. CMA doesn't apply before Kernel comes up. In the latest u-boot, I don't see mem_reserve defined in u-boot env variables. if mem_reserve is defined, it is supposed to allocate space from the end of memory going downward. in your case, it will reserve 1GB space for DSP.

    If you follow TI's set up for run_kern, defined in u-boot env
    run_kern=bootz ${loadaddr} ${rd_spec} ${fdtaddr}

    for boot=ramfs, the rd_spec should be
    init_fw_rd_ramfs=setenv rd_spec -

    By the way, I assume your boot type is similar to TI ramfs is based on the existence of uRamdisk which I assume is the filesystem.

    Hi Rex, thanks for your efforts.

    yes you are right we use ramfs like rootfs (which contains all the firmware, busybox, etc.). Are there any better ways to boot without ramfs?

    We followed your suggestion about following TI`s uboot env setup using boot=ramfs without any success. In fact all the results given above were taken this way.

    Can you check if 1GB of RAM is enough to work with lpae=1?

    Could you please give us some guidelines on how to collect diagnostic information necessary for TI to help us debug?

    Hi, Dmitry,

    On TI EVM, three boot methods are provided and it is set through boot variables, boot=net, ramfs, ubi. UBI is booting kernel from NAND which has a combined kernel and filesystem ubi imaged burnt to it. Ramfs is to boot with the kernel downloaded from tftp server, but file system on the RAM. Boot=net is booting images downloaded from network, and filesystem on NFS server.

    The RAM size has nothing to do with lpae=1. K2E needs to access memory using LPAE. The kernel will take up space of whatever the code occupies (text, stack, dss, etc) and + 128MB for internal mapping. It should be roughly 512MB +/-. You really need to see how big it takes and configure it accordingly. These are not TI or K2E specific, but generic Linux topics which you should be able to find more info from open source or linux forum.

    Hi, Rex!

    Our board uses ethernet transceivers with PHY addresses 1 and 2 (addresses 0 and 1 are used on the EVM board). Are there enough changes in keystone-k2e-evm.dts:

    &mdio {

    status = "ok";

    ethphy0: ethernet-phy@0 {

    compatible = "marvell,88E1514", "marvell,88E1510", "ethernet-phy-ieee802.3-c22";

    reg = <0>;  reg = <1>;

    };

    ethphy1: ethernet-phy@1 {
    compatible = "marvell,88E1514", "marvell,88E1510", "ethernet-phy-ieee802.3-c22";
    reg = <1>; reg = <2>;
    };

    };

    Or it is necessary to make changes still somewhere?

    Hi, Eduard,

    The reg is the PHY address, and it is correct.

    Hi Rex,

    we've advanced significantly with the board debug. The problem we are facing now is low 10G Ethernet bit speed. The best value we’ve got up to date is 1,6 Gbit/sec. We suspect it to be signal integrity problem. Are there any ways to read BER from the SoC side or from the SFP module side? Can you suggest any other ways to find the problem?
