Part Number: SK-AM62
Other Parts Discussed in Thread: SYSCONFIG
Hi Dear,
Our customer is testing the SK-AM62 evaluation board and has replaced the 2G DDR of the evaluation board with the 4G MT40A2G16.During the testing process, it was found that the following:
Unable to start using the previous SD card, switch the startup mode to USB Peripheral. After using dfu util to download tiboot3. bin to the board, it was found that the board was directly stuck and the USB port could not be connected. Unable to continue downloading files such as tiboot3. bin and u boot. img.
The SD card startup log is shown in the following figure

DFU Download Log




May I ask what is causing this exception? If DDR is replaced, does the code for uboot and kernel in the SDK need to be modified?
