AM2732: QSPI Flash setting in am2732 custom board

Part Number: AM2732

Tool/software:

Dear Experts

My team have created a custom board for am2732(AM2732CDRFHAZCER) and am checking the flash writing.

QSPI flash is MX25L51245G.

Confirm that a "CCCC" response is returned in UART boot mode.

I ran uart_uniflash.py but it stopped when writing SBL.

I guess the FLASH settings of the uart_uniflash project were not suitable for the MX25L51245G, so I changed the settings, but they are not working properly.
I cannot connect the debug probe correctly in my environment, so I cannot run the qspi_diag project.

So I tried to set it up by referring to the data sheet, but it didn't work.

I will attach the settings I made and the data sheet I referred to, so please point out any mistakes.






MX25L51245's datasheet is here

Hi all experts.
I apologize for the inconsistent formatting.
Add information. The SDK version I'm using is mcu_plus_sdk_am273x_09_02_00_52.

Dear all experts.

After further investigation, I was able to boot in NoBoot mode and obtain a list of settings by running qspi_diag project.

The reason noboot mode did not start was because the GEL file had not been configured correctly.

The contents of the SFDP I obtained are pasted below. Sorry for the trouble.
