FatFS - Cannot format drive, FR_MKFS_ABORTED

Why does USB CDC hang while receiving data?

QUESTION

FatFS - Cannot format drive, FR_MKFS_ABORTED

Asked 2021-Feb-23 at 21:17

I am new to embedded development and have been tasked with implementing a file system on SPI flash memory. I am using a w25qxx chip and an STM32F4xx on STM32CubeIDE. I have successfully created the basic i/o for the w25 over SPI, being able to write and read sectors at a time.

In my user_diskio.c I have implemented all of the needed i/o methods and have verified that they are properly linked and being called.

in my main.cpp I go to format the drive using f_mkfs(), then get the free space, and finally open and close a file. However, f_mkfs() keeps returning FR_MKFS_ABORTED. (FF_MAX_SS is set to 16384)

QUESTION

Why does USB CDC hang while receiving data?

Asked 2021-Feb-11 at 10:23

Good afternoon, I am using stm32 Blue Pill on USB (CDC) com port, "IAR" development environment. I have connected a library 1, 2 for stm32 to work with W25Qxx SPI flash drives ...

I ran the tests in the main.c file as follows: Write byte, read byte, write page, read page, sector write, sector read, block write, block read. All checks were successful, the flash drive is working and there are no problems with the library.

The problem is as follows, when I connect via app or terminal to port and try to send data in "HEX" format 1E 01 0A 02 00 00 09 C4 03, and then write them into memory by the microcontroller (W25Qxx) then USB CDC freezes (crashes) when receiving data packets on stm32 and when reconnecting a message "USB device not recognized" appears on the computer.

3.3v power did not turn off!

In order for you to check this, I will give an example:

The project was created via STM32CubeMX.

As far as I remember the function `CDC_Receive_FS()´ is a call back from the USB Interrupt. So writing to the memory directly from the IRQ is not good since it will block other interrupts.

A better solution would be to copy the receive buffer to a local structure and and set a flag. In you main loop you could monitor the flag and start the write.
