how to erase the previous data in SD card(SPI communication) by using erase command in stm32f103c8(HAL library)

[mrsmile]

in this condition using to continuously erase the data.

uint8_t erase_cmd[6]={0x20, 0x00, 0x00, 0x00, 0x00, 0x95};

HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_RESET); // Chip select pin

HAL_SPI_Transmit(&hspi1, erase_cmd, sizeof(erase_cmd), HAL_MAX_DELAY);

HAL_SPI_Receive(&hspi1, &status, 1, HAL_MAX_DELAY);

HAL_GPIO_WritePin(GPIOB, GPIO_PIN_0, GPIO_PIN_SET);

Hello @mrsmile​,

You may need to refer to the datasheet to check erase command.

Also, could you please check buffer status in the receive function?
