Hello Champs,
HW: own board based on MMWCAS-DSP-EVM, same except for adding UART function
SW:PROCESSOR_SDK_VISION_03_07_01_00
Customer is attempting to recreate a development board circuit based on the MMWCAS-DSP-EVM board circuit, using the TDA2X chip. The configuration currently in use is the tda2xx_cascade_linux_radar version. When he connected the development board to the computer, the serial port displays that the kernel is not loading.

mmc info - display info of the current MMC device
mmc read addr blk# cnt
mmc write addr blk# cnt
mmc erase blk# cnt
mmc rescan
mmc part - lists available partition on current mmc device
mmc dev [dev] [part] - show or set current mmc device [partition]
mmc list - lists available devices
mmc hwpartition [args...] - does hardware partitioning
arguments (sizes in 512-byte blocks):
[user [enh start cnt] [wrrel {on|off}]] - sets user data area attributes

Wrong Image Format for bootm command
ERROR: can't get kernel image!
The image below is a comparison of the serial output from my custom board and the MMWCAS-DSP-EVM output. Could you advise on how to modify the configuration files to enable the system to boot properly? Is it necessary to flash the onboard EEPROM?

Thanks
Regards
