SK-AM64B: SD Card Boot Failed with the Default RT Linux Image

Part Number: SK-AM64B

Hi TI Experts,

Customer is working on SK-AM64B SDK9.2.

They used SD card boot, and used the below default image of SDK9.2 RT Linux SDK.

After the HW setup, when they boot this default image, they will see the below error.

U-Boot SPL 2023.04-ga97ca328b3 (Jan 08 2024 - 08:11:13 +0000)
EEPROM not available at 0x50, trying to read at 0x51
Resetting on cold boot to workaround ErrataID:i2331
Please resend tiboot3.bin in case of UART/DFU boot
resetting ...

Please see the picture of this chip below, I think this should be the HS device right so no need to change the tiboot3.bin?

We also have tried and followed the below guide to change the gp.bin to tiboot3.bin to make it as a GP board boot.

However, this time, after this single change, there is no log in the booting anymore.

We doubted this might be a bug for SDK9.2 RT Linux SDK image, so we have also tried the RT Linux SDK image in SDK8.6.

But we faced the same issue in SDK8.6 also.

Could you provide us any advice please?

Thanks a lot!

Hi TI Experts,

We thought this problem might related the rt-linux default image, so we tested and used non-rt linux default image in SDK9.2, but facing the same problem discussed above.

Please help on this, thanks!

Hi TI Experts,

We have double confirmed that our AM64B-SK is the HS device, so we do not need to do anything about the default tiboo3.bin. But we do not know why still face the problem here.

I have found a previous regarding to this same problem shown below, but it is based on SDK9.1.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1314269/sk-am64b-sk-am64b-cannot-boot

Based on the discussions in this thread, I think we should have solved this problem in SDK9.2 already, so not sure why still having this problem.

Thanks for your help!
