Tool/software:
hello. I am contacting you because I have built an AM6252 board based on Beagleplay and it fails to boot with the same SD card.
Additionally, I followed 3.1.1.7.1. Booting U-Boot from the console UART using the SDK.
First of all, AP uses AM6252ASGGHAALW and there is no storage device such as eeprom. I removed as much unnecessary circuits as possible.
1. I tested it by writing beagleplay-emmc-flasher-debian-12.7-minimal-arm64-2024-09-04-8gb.img.xz and tisdk-thinlinux-image-am62xx-evm.wic.xz to an SD card, and additionally tested it with an SD card that only had the SDK's tiboot3.bin, tispl.bin, and u-boot.img files in it, but it did not work.
2. Tested using U-Boot boot method from console UART using SDK.
2.1. ti-processor-sdk-linux-rt-am62xx-evm-09.01.00.08-Linux-x86-Install.bin
2-2. ti-processor-sdk-linux-rt-am62xx-evm-10.00.07.04-Linux-x86-Install.bin
We conducted tests with the two versions above.

### ERROR ### Please RESET the board ###
The output is as above
Additionally, the information confirmed using parse_uart_boot_socid.py is as follows.
SoC ID Header Info:
('NumBlocks : ', 2)

How can I solve the above problem?
Please answer my question. Thank you in advance.
