STM32 Mikromedia Bootloader problem

[umut3502]

I have a STM32 Mikromedia . I programmed this with bootloader but yesterday when I was programing with bootloader,
PC was locked and so maybe bootloader is broken. When I plugged usb to PC only TFT screen was white. when I press the reset button nothing is happened.

How can I programme my cart. Can the bootloader be broken?

What can I do? Please help me

Hello,

It's possible that locking of the PC caused the fault in bootloader.

If you have external programmer, or you know someone who owns it, you can re-program the bootloader firmware which is available for download from mikromedia board web page.

Best regards.

Hello,

Please make sure that you have downloaded bootloader firmware for correct mikromedia board.
mikromedia for STM32 M3
mikromedia for STM32 M4

Also, you should try programming some example project for mikromedia STM32 board with your external programmer to test the MCU.

Best regards.

I solved this problem. problem is Jtag or Swd First when I selected Jtag the bootloader didn't work but when I selected swd the bootloader worked very good. What difference is between Jtag and swd? I don't know. Can you give me to an information this issue?
