How can I update the software on STM32F7 ?

[MMerc.1]

Hi,

I want to update the software of the STM32F746BGT via a USB stick or Ethernet connexion.

Firstly, how can I use the USB stick to update the software inside the MCU ?

How can I use the Internet connexion (via UART : Lantronix XPORT) to update the software inside the MCU ?

Best regards

Partition your code into a bootloader and the real application. The bootloader normally just starts the real app. When some condition is set to true, the bootloader instead communicates with the peripheral(s), downloads + flashes a new version of the app into the flash and finally reboots.

Hi,

Do you think the example of "STM32Cube_FW_F7_V1.16.0\Projects\STM32756G_EVAL\Applications\USB_Host\FWupgrade_Standalone" works ?

Hi,

I try to use the example of "STM32Cube_FW_F7_V1.16.0\Projects\STM32756G_EVAL\Applications\USB_Host\FWupgrade_Standalone" but when I add "#include <usbh_def.h>" in order to use the structure for "extern USBH_HandleTypeDef hUsbHostFS" in main.h I have the following error :

Do you have any idea about this error ?

For me it is too less information. Can you share your project or this library? How this variables are declared? For example "USBH_MAX_NUM_ENDPOINTS". Are they as #define? Looks like the compiler can't find their declarations.

Hi,

I fixed the error. But now, I am trying to figure out how it works.

I call the function "HCD_Port_IRQHandler" and I have to call the function "HAL_HCD_PortEnabled_Callback". Unfortunately, the variable "hprt0" does not have a "USB_OTG_HPRT_PENA" bit... So function "HAL_HCD_PortEnabled_Callback" is never called.

Do you know why ?

Edit 1 :

I fixed the error. Now in case "HOST_CHECK_CLASS" in the function "USBH_Process", I don't have "USBH_OK" when I use "phost->pActiveClass->Init(phost)".

Do you know why ?

Edit 2 :

The problem is in the function "static USBH_StatusTypeDef USBH_MSC_InterfaceInit(USBH_HandleTypeDef *phost)" :

phost->pActiveClass->pData = (MSC_HandleTypeDef *)USBH_malloc(sizeof(MSC_HandleTypeDef));
 MSC_Handle = (MSC_HandleTypeDef *) phost->pActiveClass->pData;

MSC_Handle return NULL value.

From this little part of the code I conclude that USBH_malloc can't allocate memory. Malloc returns NULL when it can't allocate enough space.
