Other Parts Discussed in Thread: UNIFLASH
Hi, TI experts.
We are trying to test a new board, changed from EVM-GP board of Am64x, and encountered Uart flash problem.
The board is installed with SOC of Am6411 and LPDDR4, eMMC for memory / storage. Besides a NOR flash is installed.
Uart_flash.py tool is used for Rom flash, we failed in flashing neither NOR flash nor eMMC.
Step 1: Transfer sbl_uart_uniflash.tiimage, succeeded.
Step 2: No response ...
* I knew the prebuilt tiimage of sbl_uart_uniflash will use DDR that do not match our hardware, a LPDDR4 version is rebuilt to replace it.
Then I tested sbl_null.release.tiimage. The same result which failed at step 2.
Obviously, the DMSC rom started and can receive SBL at Uart boot mode.
I doubt that, the ROM code (DMSC) failed to start the received SBL, which may be caused by some hardware issue of the new board.
When the board is set as UART boot mode, a response message is received from DMSC as the blowing.
Could it be analyzed to tell us some information about the boot status?
What are the necessary hardware configuration?
And any other thing we could investigate ?
Regards.
