Have the function verified on all parts of STM32?

different flash size or different package?

What should I check if upload OK, but erase and download fail?

For the st bootloader programmers:

to enable using ports greater than COM9 use the following filename pattern, shown for com19:

\\.\COM19

For sprintf: ''\\\\.\\COM%d''.

I have my stm32f103 hooked up to an RN41 bluetooth to serial port module and my PC's bluetooth serial port emulator really wants to use COM10 or com11.

I got this from the source code for teraterm.

Dear John,

On all our current production devices (B and Z) we have only version 2.0 of bootloader programmed by ST in System Memory area at our manufacturing since now. And for the PC Windows Software we have released only one version 1.0 till now and you can download it with this direct link :

.

I have seen some people facing some issues in the past and it was due to some HW mistakes on Using USART1 TX and RX pins and try also to modify to a lower baudrate with full POR reset at each time. Hope this helps you to get clear picture.

Cheers,

STOne-32. :o
