I'm using STM32H753 eval board and trying to implement memory tests like data, address pins short, memory cell corrupted etc. on this eval baord there is MT28EW128ABA1LPC-0SIT.
for testing address pins short detection I've shorted A4 and A5 pins but HAL_NOR_Init function goes to error handler because it reads CommandSet as 0xFFFF which doesn't match to Fujitsu/ Intel command set so it enters into error handler.
/* Get the value of the command set */
NOR_WRITE(NOR_ADDR_SHIFT(deviceaddress, uwNORMemoryDataWidth, NOR_CMD_ADDRESS_FIRST_CFI), NOR_CMD_DATA_CFI);
hnor->CommandSet = *(__IO uint16_t *) NOR_ADDR_SHIFT(deviceaddress, uwNORMemoryDataWidth, NOR_ADDRESS_COMMAND_SET);
status = HAL_NOR_ReturnToReadMode(hnor);
I've referred MT28EW128ABA1LPC-0SIT datasheet for its behavior in case of address lines short but did not find any solution.
anybody has any clue on it?
