Hi, I tried to run the FWupgrade_Standalone example on the STM32h743I EVAL Rev B board, but it didn't work.
There are currently three issues
1.HS, FS in the build settings are not working correctly.
If I don't connect a USB stick to the OTG HS without covering HS and FS, the red LED blinks. According to the readme, it seems to be USB Disconnect. When I built the example with FS, I removed the jumper on JP2 as instructed in the readme.
2.The example says that the download command is executed if the tamper switch is pressed for less than 3 seconds, but my board goes into download mode by itself without pressing the tamper switch.
3.After checking with the debugger, my board keeps returning URB_State_IDLE on line 192 of the usbh_msc_bot.c file(line 13 of the following code),
switch (MSC_Handle->hbot.state)
{
case BOT_SEND_CBW:
MSC_Handle->hbot.cbw.field.LUN = lun;
MSC_Handle->hbot.state = BOT_SEND_CBW_WAIT;
(void)USBH_BulkSendData(phost, MSC_Handle->hbot.cbw.data,
BOT_CBW_LENGTH, MSC_Handle->OutPipe, 1U);
break;
case BOT_SEND_CBW_WAIT:
URB_Status = USBH_LL_GetURBState(phost, MSC_Handle->OutPipe);
if (URB_Status == USBH_URB_DONE)
{
if (MSC_Handle->hbot.cbw.field.DataTransferLength != 0U)
{
/* If there is Data Transfer Stage */
if (((MSC_Handle->hbot.cbw.field.Flags) & USB_REQ_DIR_MASK) == USB_D2H)
{
/* Data Direction is IN */
MSC_Handle->hbot.state = BOT_DATA_IN;
}
else
{
/* Data Direction is OUT */
MSC_Handle->hbot.state = BOT_DATA_OUT;
}
}
which causes it to return usbh_busy on line 798 of the usbh_msc.c file,
while (USBH_MSC_RdWrProcess(phost, lun) == USBH_BUSY)
{
if (((phost->Timer - timeout) > (10000U * length)) || (phost->device.is_connected == 0U))
{
MSC_Handle->state = MSC_IDLE;
return USBH_FAIL;
}
}
MSC_Handle->state = MSC_IDLE;
so it seems to be stuck in a while statement.
I installed the latest version of the Cube MCU Package for the H743I EVAL board from CubeMX, and did not modify the example code.
Does anyone have a solution or advice for this problem?

Hi @Croaker
Check SB50. It must be removed as well as detailed in the user manual.
