STM bootloader problem
Posted: Sun Jun 18, 2023 3:01 am
Hi all
I have purchased an STM32F103C8, and am having some problems.
I purchased this of ebay, and I assume its a Chinese clone , without bootloader. I can install the arduino bootloader via stmcube and I return the boot jumper to its origional position and hit reset before removing power. I can then load a program using Arduino via usb. But immediately when the program finishes loading (succesfully) a message comes up and says there is no longer a usb connection, it appears the bootloader has been erased. I can reload the bootloader, but unless I do a full erase beforehand Arduino doesnt see any com port.
I hope someone can shed some light on this problem.
Regards Larry
