Hello,

I have a STM32F103RBT6 board and i was playing with it. I sent some codes about sending some characters via USART1. Now my board rejects to download firmware on bootloader. But when i set in run mode, my program works.

Is there any chance to renew bootloader or fix it?

Thanks in advance

I presume you are talking about the ST bootloader. The ST bootloader is not writeable so you don't need to renew or fix it. Have you checked boot0 and boot1 pin states when you are trying to access the bootloader? Are you using a development board and if so which one.
