AM62A7: Problems with porting u-boot to a custom card

Gustav Malmstrom

Part Number: AM62A7
Other Parts Discussed in Thread: SK-AM62A-LP, SYSCONFIG

Hello, we have a custom built card that I am having problems getting to boot to u-boot.

We do not have the same DDR memory as the SK-AM62A-LP board. Because of that I have followed the instructions at: Porting U-Boot and AM62Ax MCU+ SDK: DDR (ti.com) to generate a new DDR config using SysConfig (ti.com).

With my new DDR config the card seems to get further in the boot process, but not all the way. Could you help me determine if it is still a DDR problem? And how I can proceed with debugging?

Printout from boot:

Hi,

Thank you for sharing the error logs, I will check this and get back with more information.

Regards,

Hi,

Can you check if you can see logs from DM on other UART port?
Meanwhile, could you also try booting from a different boot media like UART/DFU to check if it boots from there or not?

Since, DDR initialization is done and the logs are past that stage, most likely there is no issue with DDR configuration.
I will check internally, what are the ways to debug this.

Regards,
Aparna

Hello,

I do not get any printout on the other UART ports.

I can try booting using other media, but I am not really sure how. I will have to look into that.

Thank you.

Hello again,

We have made progress!
We removed the ddr config in the R5F sysconfig and only has the .dtsi file. I read the README from the syscfg tool wrong ( dev.ti.com/tirex/content/Processor_DDR_Config_0.10.01.0000/docs/README.html)

Now the DM UART prints:

We looked with the debugger and we are on program counter 0x9CA30138, which looks like it is in the DDR memory.

But we still have problems with the main domain boot.
We get the following printout:

Could it be a problem with our bl31.bin (ATF) file?

Hello,

New update.

It was the BL31.bin file that was bad, I used one I built using the ATF repository. When I used the one included in the SDK it gets to the u-boot prompt.

But it will not boot to linux...

The following log is when i let it autoboot:

Do you have any leads on what could be causing the Kernel panic from this?

Hi,

Have you been following the Porting Kernel guide: Porting Kernel

Are you able to boot with minimal DTS configuration?

Regards,
Aparna

Hello,

Yes, I tried that but when I follow the guide I get build errors.

The ti-linux-kernal is unmodified, apart from the hello-world.dts and Makefile adjustment that the guide tells me to do.

I think the build command is outdated.

I am using make ARCH=arm64 CROSS_COMPILE='aarch64-linux-gnu-' dtbs
instead of
make ARCH=arm64 CROSS_COMPILE='aarch64-none-linux-gnu-' dtbs

From what I have seen before is the aarch64-none-linux-gnu compile option is for older SDK, so more things might have been changed.

Hi,

There is a follow up thread: (9) AM62A7: Problems with following Linux Board Port guide for custom board - Processors forum - Processors - TI E2E support forums

Closing this one, we can continue discussion on the other thread.

Regards,
Aparna
