Hello everyone, please advise, I encountered difficulties when removing and installing memory read protection when programming h503 via the built-in UART bootloader.
I use commands {0x92, 0x6D} to remove read protection and {0x82, 0x7D} to install read protection. On F103 these functions work correctly, on h503 they do not.
At the same time, on 503, memory erase, ID reading and programming operations work correctly, the h503 microcontroller is flashed and after rebooting the new program takes effect.
Perhaps I am sending incorrect read protection codes? Or is my mistake in something else?
