AM623: Custom board bring-up trouble

Hi,

Can you provide boot log.

~ Judith

Hi Judith,

When I wrote this I wasn't getting a boot log, I was only able to see bus activity for the SD card. I've since went and rebuilt all bootloader stages and ensured I was using the HS_FS images with our DDR timings. I have SPL logs now, but for some reason u-boot is trying to read the environment/next stages from MMC2.

MMC0 -> eMMC which is currently blank
MMC1 -> SD card which we're using for bringup
MMC2 -> CC3300 WiFi

I'm currently trying to understand the reason for the references to MMC2

Hi Graham,

On AM62x Processor SDK, MMC2 is SD card, see log below:

Not sure what changes you have done in u-boot, but perhaps you might be confusing SD card boot mode for WIFI.

~ Judith

All right I'll consider the MMC2 message a red herring, then.

The only change's I've made to u-boot are:

• modify arch/arm/dts/k3-am62x-sk-ddr4-1600MTs.dtsi to use output from SysConfig for our DDR part
• add #define DEBUG to several files and add a couple more debug() lines to a few files
• disable a couple of SPI flash drivers because adding #define DEBUG made the R5 SPL too large

Hi Graham,

Your ATF and OPTEE are working properly, I built my  binaries with extra options.

Based on the following error:
--> Check if pads/pull-ups of bus are properly configured

It seems like a configurations error. Looking through u-boot, found this print in i2c driver, so it seems like the bus pads have not been configured for i2c and/or pull-ups are missing.

Please look at: https://dev.ti.com/tirex/explore/node?node=A__ANjtmn.T3uPBiF9U2lCRWQ__linux_academy_am62x__XaWts8R__LATEST

• Establish an initial minimal pinmux setup for the custom board
• Update PMIC configuration
• Customize console UART settings:

I would first do the following step: Establish an initial minimal pinmux setup for the custom board since a minimal pinmux setup is needed to avoid signal conflicts that may occur when running a TI EVM pinmux configuration on a custom board that has different pinmux requirements.

~ Judith

Yeah the minimal pinmux was what I was working on when I encountered this issue.

The i2c errors were from main_i2c1 probing for the SK's i2c gpio expander. I've gotten a u-boot prompt now and a partially booting linux kernel. I'll focus on u-boot for now.

There's more stripping down of the device tree/defconfig and writing a board file, but at this point I have a u-boot console and a partially booting kernel.

I dropped the RAM size, per https://dev.ti.com/tirex/explore/content/linux-academy-AM62X-8.6.0.42.v1/ch-porting/porting-uboot.html#modifying-ram-size, since we're not using a 4 Gbit RAM part. But I'm seeing error's mentioned in other E2E threads. Namely, errors related to the reserved regions

Hi Graham,

Since you have 2GB DDR, you should not have issues with memory region failed error. Everything should fit withing 512 MB of DDR memory.

It may be an issue with your DTB. You could check the DTB you generated by using:

$ dtc -I dtb -O dts <dtb-name>.dtb

~ Judith

Hi Judith, I was pulled to something else for a few weeks and am back on bringup, now.

We don't have 2GB we have 512MB (single 4Gbit chip). From what I see, it looks like we're running into the same issue in the am625 thread linked previously. When u-boot boots linux we get similar

ERROR: reserving fdt memory region failed

that the bdinfo command returns.

Boot-wise the kernel appears to boot with a few errors and no panics, but we're not getting a login prompt on the serial port.

Hi,

Ok, currently we do not have an example in our SDK using 512 MB of DDR.

You say kernel appears to boot with no panic, can you show where Linux boot fails?

I assume it is not the same log you showed before, since that log does not boot kernel Image.

The following doc has a few more hints on debugging: https://dev.ti.com/tirex/explore/node?node=A__ANjtmn.T3uPBiF9U2lCRWQ__linux_academy_am62x__XaWts8R__LATEST

• Use printf()-style debugging when JTAG is not available or not practical.

• Maximizing the usefulness of this approach usually requires the early (debug) UART to be configured and activated (which will happen as part of SPL’s board_init_f()). Most of the critical low-level code on current TI EVMs is executed while the regular console UART is not yet available. If the early UART is not activated, nothing would get printed during failures relating to boot, PMIC setup, clock setup, DDR setup, and other critical stages. This leads to “black screen” failures which provide no feedback as to what the problem may be and how to debug it.

• Many U-Boot modules (source files) already contain various forms of debug() print statements which can be activated on a per-module basis by adding a #define DEBUG to the top of the source file.

• Beyond that, it can be helpful to add print statements throughout the boot flow to trace program execution. For example, the printf statement shown below can be inserted into code to help debug: printf("%s: %d:\n", __func__, __LINE__);.
  
  
  Perhaps another method that could be used to debug is shown in the following thread:

  https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1247051/sk-am62-debugging-spl-in-ccs

Thank you for your patience

Hi,

I believe it is already escalated.

For the moment it seems like the rootfs is not being mounted.

OK I first ran "mmc part" it was telling me unknown partition table type. So I reflashed my SD card using bmap-tool. Then I realized when running "mmc list" and "mmc dev" that u-boot was defaulting to the blank eMMC. (All that is to say: my UUIDs have changed since yesterday.)

After running "mmc dev 1", "mmc part" returns the partitions and UUIDs correctly.

If I let the boot run uninterfered or if I follow the commands you ran in your log above, the UUID matches the rootfs UUID from "mmc part"

See attached log.

My suspicion is that previous errors from loading/booting are the actual culprit.

Hi,

It seems like kernel was enable to open /dev/console:

/* Open /dev/console, for stdin/stdout/stderr, this should never fail */
void __init console_on_rootfs(void)
{
	struct file *file = filp_open("/dev/console", O_RDWR, 0);

	if (IS_ERR(file)) {
		pr_err("Warning: unable to open an initial console.\n");
		return;
	}

This leads back to the following:

    Establish an initial minimal pinmux setup for the custom board:

            A minimal pinmux setup is needed to avoid signal conflicts that may occur when running a TI EVM pinmux configuration on a custom board that has different pinmux requirements.

            Pinmux performed in U-Boot is usually limited to:

                the peripherals that are directly involved in the boot process (such as GPMC, DDR, MMC, SPI, etc.)

                an I2C module used for PMIC connectivity

                the console UART

            The TI-provided Pin MUX Utility in SysConfig is the recommended way to generate pinmux settings for a custom board.

    Customize console UART settings:

            Configure the desired console index using the Kconfig tool.

I had left the hello world kernel device tree relatively untouched since I was focused on the u-boot errors. (I had disabled a few nodes that prevented compiling and configured the memory node for 512MB).

The hello world device tree only has main_uart0 and main_uart1 enabled, but it needed an alias to tell the kernel that main_uart0 is /dev/ttyS2. I added that which solved the console error.

At this point I'm getting to a login prompt and have plenty of errors to resolve. But I do want to focus back on the "memory-region errors" from u-boot and the "cma: Failed to reserve 512 MiB" from Linux

At this point I'm getting to a login prompt and have plenty of errors to resolve. But I do want to focus back on the "memory-region errors" from u-boot and the "cma: Failed to reserve 512 MiB" from Linux

Can you please look at the below commit, and apply something like this to your DTS fileL

arm64: dts: ti: k3-am62x-sk-common: Reserve 128MiB of global CMA
https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/?h=ti-linux-6.1.y&id=8ed8775c45bf9c02a06b8accfc6bc2b6deb353bb

The commit is part of our ti-linux-6.1.y tree used for SDK v9.x.

Regards, Andreas

As for the U-Boot error, there's a section in an app note (below) that might be helpful...

Minimal Platform Development on AM62x Devices
https://www.ti.com/lit/pdf/spradd1

Please let me know if this addresses the warning messages seen during U-Boot startup.

Regards, Andreas

I have add #define CFG_PRAM (250 * 1024)  in the  file (include/configs/am62x_evm.h) .but it didn't work. 
you can see I grep CFG_PARM. it is  just used once >

Hi Helen,

please allow a couple of days for a response. Thanks for your patience.

Regards, Andreas

it is working . my problem has solved.Thanks very much ! 
for 512Ram. the gd->ram_size set to (256+128)M , it is ok .

Helen, thank you so much for closing the loop, such feedback is very important to us! Regards, Andreas

Actually I just noticed why this approach didn't work for you. You tried using it in the context of SDK v8.6 (which uses ti-u-boot-2021.01), and in this U-Boot version the CFG_PARM feature did not exist yet, so adding this definition didn't do anything. So yes the other approach we discussed is better/more suitable especially in an SDK v8.6 context.
