Problem with interfacing with S26KL128S flash chip
Dear All,
I have a board that uses the STM32U599NJH6Q as MCU and the S26KL128S is attached to the OCTOSPI1 peripheral of the said MCU.
I need to be able to erase a sector and/or a page, write data to the device and then be able to read them back.
What I am unsure of at the moment is the initialization code. Specifically, I am not sure if I need to use Octo SPI mode or Hyperbus.
Currently I am going with Octo SPI and my MX_OCTOSPI1_Init looks like this:
void MX_OCTOSPI1_Init(void)
{
/* USER CODE BEGIN OCTOSPI1_Init 0 */
/* USER CODE END OCTOSPI1_Init 0 */
OSPIM_CfgTypeDef sOspiManagerCfg = {0};
HAL_OSPI_DLYB_CfgTypeDef HAL_OSPI_DLYB_Cfg_Struct = {0};
/* USER CODE BEGIN OCTOSPI1_Init 1 */
/* USER CODE END OCTOSPI1_Init 1 */
hospi1.Instance = OCTOSPI1;
hospi1.Init.FifoThreshold = 4;
hospi1.Init.DualQuad = HAL_OSPI_DUALQUAD_DISABLE;
hospi1.Init.MemoryType = HAL_OSPI_MEMTYPE_MACRONIX;
hospi1.Init.DeviceSize = 26;
hospi1.Init.ChipSelectHighTime = 2;
hospi1.Init.FreeRunningClock = HAL_OSPI_FREERUNCLK_DISABLE;
hospi1.Init.ClockMode = HAL_OSPI_CLOCK_MODE_0;
hospi1.Init.WrapSize = HAL_OSPI_WRAP_NOT_SUPPORTED;
hospi1.Init.ClockPrescaler = 4;
hospi1.Init.SampleShifting = HAL_OSPI_SAMPLE_SHIFTING_NONE;
hospi1.Init.DelayHoldQuarterCycle = HAL_OSPI_DHQC_ENABLE;
hospi1.Init.ChipSelectBoundary = 0;
hospi1.Init.DelayBlockBypass = HAL_OSPI_DELAY_BLOCK_BYPASSED;
hospi1.Init.MaxTran = 0;
hospi1.Init.Refresh = 0;
if (HAL_OSPI_Init(&hospi1) != HAL_OK)
{
Error_Handler();
}
sOspiManagerCfg.ClkPort = 1;
sOspiManagerCfg.DQSPort = 1;
sOspiManagerCfg.NCSPort = 1;
sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_LOW;
sOspiManagerCfg.IOHighPort = HAL_OSPIM_IOPORT_1_HIGH;
if (HAL_OSPIM_Config(&hospi1, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
{
Error_Handler();
}
HAL_OSPI_DLYB_Cfg_Struct.Units = 0;
HAL_OSPI_DLYB_Cfg_Struct.PhaseSel = 0;
if (HAL_OSPI_DLYB_SetConfig(&hospi1, &HAL_OSPI_DLYB_Cfg_Struct) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN OCTOSPI1_Init 2 */
/* USER CODE END OCTOSPI1_Init 2 */
}In my main I am doing the following:
uint8_t ofTxBuffer[] = " **OCTOSPI Flash sample**\r\n";
int main(void)
{
HAL_Init();
....
MX_OCTOSPI1_Init();
...
// Configure the memory-mapped mode for S26KL128S
OSPI_MemoryMappedTypeDef mMemMappedCfg = {0};
// Set command to enter memory-mapped mode
OSPI_RegularCmdTypeDef mCommand = {0};
mCommand.OperationType = HAL_OSPI_OPTYPE_COMMON_CFG;
mCommand.FlashId = HAL_OSPI_FLASH_ID_1;
mCommand.InstructionMode = HAL_OSPI_INSTRUCTION_1_LINE;
mCommand.Instruction = 0x00; // Enter the appropriate instruction here
mCommand.AddressMode = HAL_OSPI_ADDRESS_1_LINE;
mCommand.AddressSize = HAL_OSPI_ADDRESS_24_BITS;
mCommand.Address = 0x000000; // Start address of the flash memory
mCommand.DataMode = HAL_OSPI_DATA_1_LINE;
mCommand.NbData = 1;
mCommand.DummyCycles = 0;
mCommand.DQSMode = HAL_OSPI_DQS_DISABLE;
mCommand.SIOOMode = HAL_OSPI_SIOO_INST_EVERY_CMD;
if (HAL_OSPI_Command(&hospi1, &mCommand, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK) {
// Initialization Error
Error_Handler();
}
// Configure memory-mapped mode
mMemMappedCfg.TimeOutActivation = HAL_OSPI_TIMEOUT_COUNTER_DISABLE;
if (HAL_OSPI_MemoryMapped(&hospi1, &mMemMappedCfg) != HAL_OK) {
// Initialization Error
Error_Handler();
}
__IO uint8_t *mem_addr;
mem_addr = (__IO uint8_t *)(OCTOSPI1_BASE);
memcpy(mem_addr, &ofTxBuffer, sizeof(ofTxBuffer));
uint8_t octoFLASHData[128] = {0};
mem_addr = (__IO uint8_t *)(OCTOSPI1_BASE);
memcpy(&octoFLASHData, mem_addr, sizeof(ofTxBuffer));
printk("String in octo flash: %s\r\n", octoFLASHData);
while(1){}
}Once the code hits the memcpy point I am getting a hardfault.
Furthermore it is unclear to me how to proceed with actually erasing the flash.
Any help would be great.
