Hello @Sansel 

 What is the error you are getting? Are you using SDIO or SPI driver? 

Could you please share with us the content of SDIO or SPI register when getting the error?

Hi [Saket_Om],

Thank you for your inquiry regarding the error we are encountering.

### Driver in Use We are using the **SDIO driver** to interface with the SD Card.

 

void MX_SDIO_SD_Init(void) {

hsd.Instance = SDIO;

hsd.Init.ClockEdge = SDIO_CLOCK_EDGE_RISING;

hsd.Init.ClockBypass = SDIO_CLOCK_BYPASS_DISABLE;

hsd.Init.ClockPowerSave = SDIO_CLOCK_POWER_SAVE_DISABLE;

hsd.Init.BusWide = SDIO_BUS_WIDE_1B;

hsd.Init.HardwareFlowControl = SDIO_HARDWARE_FLOW_CONTROL_DISABLE;

hsd.Init.ClockDiv = 5;

if (HAL_SD_Init(&hsd) != HAL_OK) { Error_Handler(); } // Enable wide bus operation (4-bit mode)

if (HAL_SD_ConfigWideBusOperation(&hsd, SDIO_BUS_WIDE_4B) != HAL_OK)

{ Error_Handler(); }

}

Solution : dont use this "hp" card.

Where you buy it ? (google shows no source for sd-cards by hp ! )

So maybe same fake product, like my "Lenovo" sd-card from aliexpress (google shows no source for sd-cards by Lenovo ! )
