Stm32h743 is connected via FMC s29gl064s，and cubeide configed. As shown below:
RCC configured as below：
Read flash ID：
sts = HAL_NOR_Read_ID(&hnor1, &id);
printf("sts1 = %d\n", sts);
printf("nor_id = %04x %04x %04x %04x\n",
id.Manufacturer_Code,
id.Device_Code1,
id.Device_Code2,
id.Device_Code3);
HAL_Delay(1);
Return：nor_id = 0001 227e 2213 2201
Then ReturnToReadMode:
sts = HAL_NOR_ReturnToReadMode(&hnor1);
printf("stsreadmode2 = %d\n", sts);
HAL_Delay(1);
EraseChip：
sts = HAL_NOR_Erase_Block(&hnor1, 0, 0x60000000);
printf("sts_erase_block = %d\n", sts);
do {
sts = HAL_NOR_GetStatus(&hnor1, 0x60000000, 500);
printf("HAL_NOR_GetStatus1 = %d\n", sts);
} while(sts);
Return status look like correct.
Write operation：
uint16_t txbuf[1024] = {0}, rxbuf[1024] = {0};
#if 1
for (i = 0; i < 1024; i++) {
txbuf[i] = 0x5a;
}
#endif
sts = HAL_NOR_ProgramBuffer(&hnor1, 0, txbuf, 256);
printf("sts_write_buf = %d\n", sts);
do {
sts = HAL_NOR_GetStatus(&hnor1, 0x60000000, 500);
printf("HAL_NOR_GetStatus1 = %d\n", sts);
} while(sts);
Return status look like correct.
Read operation：
sts = HAL_NOR_ReadBuffer(&hnor1, 0, rxbuf, 256);
printf("sts_read_buf = %d\n", sts);
#if 1
do {
sts = HAL_NOR_GetStatus(&hnor1, 0x60000000, 500);
printf("HAL_NOR_GetStatus1 = %d\n", sts);
} while(sts);
#endif
for (i = 0; i < 256; i++) {
if (!(i % 8)) {
printf("\n");
}
printf("%04X ", rxbuf[i]);
}
printf("\n");
Return resaults as below：
According to your tips, I added the HAL_NOR_ReturnToReadMode function.
But the result is still incorrect! Please help me look again. What's the problem。
Thanks.
