STM32H7 USB, SD Card and ADC problem

[vahidajalluian]

Since my forum account has been banned, I'm reporting bugs here instead.

Describe the set-up
I am using a custom board with the following specifications:

MCU: STM32H743BIT6
STM32CubeMX version: 6.13
H7 firmware version: V1.12.0

Describe the bug
When one create project from scratch with stm32cubemx these bugs will appear.

1- USB Device Descriptor Issue with Optimizations
I had also this problem with f4 series, when enabling optimization (o1 and above), USB device descriptor cannot be estimated, and therefore no device is presented Device manager of windows.
Solution: Modify the Get_SerialNum function in usbd_desc.c as follows:

static void Get_SerialNum(void)
{
  uint32_t deviceserial0;
  uint32_t deviceserial1;
  uint32_t deviceserial2;

  deviceserial0 = *(uint32_t *) DEVICE_ID1;
  deviceserial1 = *(uint32_t *) DEVICE_ID2;
  deviceserial2 = *(uint32_t *) DEVICE_ID3;

  deviceserial0 += deviceserial2;

//  if (deviceserial0 != 0)
//  {
//    IntToUnicode(deviceserial0, &USBD_StringSerial[2], 8);
//    IntToUnicode(deviceserial1, &USBD_StringSerial[18], 4);
//  }

  USBD_StringSerial[2] = 'D';
  USBD_StringSerial[4] = 'E';
  USBD_StringSerial[6] = 'V';
  USBD_StringSerial[8] = 'M';
  USBD_StringSerial[10] = 'E';
}

2-USB HS Pin Configuration Issue

Enabling USB HS in device-only mode forces PB13 to take on an alternate function, but the specific function is unclear. Despite configuring PB13 as an input, the pin behavior was erratic, and how hard I have tried, I couldn't understand what is the problem, so I switched to USB FS peripheral.

3- Enabling USB does not automatically set the USB clock to 48 MHz, causing the USB to be unrecognizable by endpoint systems.

4- Enabling SDMMC and Fatfs, I could not make it work and emulate the SDCARD. However in F4 series program I had earlier, I saw that it was forcibly enabled NVIC, so I had enabled the NVIC and the problem solved.

5- (IOC file included) In ADC, I had set the resolution to be 12 bit for both ADC1 and ADC3, but only ADC1 is affected and ADC3 is generated without setting(and so the code presume it as 16 bit) although I have checked and it has been set to be 12 bit in IOC file.

Hi @vahidajalluian,

Really sorry to hear your account has been disabled. Thank you for the above report. I have a request though. Would you mind logging a different issue for each one of problems 4 and 5, as they relate to two other topics than the USB?

Thank you,

@ALABSTM I have created two new issues for item 4 and 5.
And for those who don't know why my account has been disabled, It has been disabled, purely for being in Iran :( .
