Posted on February 12, 2018 at 13:42Hi,
I am doing a project using STM32L432KC controller and EPCQ256 (32MegaBytes) -QSPI flash, Here I am able to Erase, Write and Read. but I am able to write only 1-4 MegaBytes and then writing is gets stopped (Here I attached a Screenshot where it is get's stopped).
I tried enabling 4ByteAddressMode using below code still it is giving same problem.... is there any Bug in my below Function,
QSPI_StatusTypeDef QSPI_ENABLE_4BYTE_MODE(void)
{
QSPI_CommandTypeDef sCommand;
QSPI_WriteEnable(&hqspi);
sCommand.InstructionMode = QSPI_INSTRUCTION_1_LINE;
sCommand.Instruction = ENTER_4_BYTE_ADDR_MODE_CMD;
sCommand.AddressMode = QSPI_ADDRESS_NONE;
sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE;
sCommand.DataMode = QSPI_DATA_1_LINE;
sCommand.DummyCycles = 0;
sCommand.DdrMode = QSPI_DDR_MODE_DISABLE;
sCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY;
sCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD;
sCommand.NbData = 0;
if (HAL_QSPI_Command(&hqspi, &sCommand, HAL_QPSI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
{
Error_Handler();
}
}
please suggest me how to write Full-Flash-Memory
