Part Number: AM2432
Tool/software:
SDK: mcu_plus_sdk_am243x_09_02_01_05
CCS: 12.7.0.00007
chip: am2432ALV
example: C:\ti\mcu_plus_sdk_am243x_09_02_01_05\examples\drivers\gpmc\gpmc_flash_io
nand: MT29F4G08ABBFAH4-AATF
We used the gpmc_io demo to test our nand chip. This same nand chip(MT29F4G08ABBFAH4-AATF) tested well in our another project with gpmc_flash_io in mcu_plus_sdk_am64x_09_00_00_35
While we run on AM2432 with mcu_plus_sdk_am243x_09_02_01_05\examples\drivers\gpmc\gpmc_flash_io, it failed.
Debugging with TDMSEMU110-U, Flash_open() executed correctly, we can get devID(0000AC80) and manID(0000002C). I adapted test code according to them.
But, it executed failed at Flash_eraseBlk().
Debugging with TDMSEMU110-U, it executed at Flash_nandGpmcErase->GPMC_writeNandCommand, the exact points are below, status is SystemP_FAILURE
status += GPMC_waitPinInteruptStatusReadyWaitTimeout(handle,cmdParams->waitTimeout);
status += GPMC_waitPinStatusReadyWaitTimeout(handle, GPMC_WAIT_PIN_STATUS_WAIT_TIME_MIN);
The API Flash_open() also called GPMC_writeNandCommand() and executed well, so in my opinion, the hardware is ok.
There are some difference between am243x_sdk and am64x_adk, are there any parameters need to be changed??
Waiting for your reply, thanks.
Codes of demo are below:
