I want to flash a load on the STM32F0CB using the STM Flash Loader demo. My configuration is: 57600, Data Bits:8, Parity: Even, Echo: Disabled, Timeout: 10.I also tried with parities Odd and None.
After resetting the MCU, I get the error: "Cannot get available commands, Please, Try to change Echo selection, Reset your device then try again...". I changed the Echo selection mode with the same bad result.
So I tested with serial tool. First of all, the only baud rates which gave a valid reply (ACK: 0x79, NACK: 0x1F) were 56000 and 57600. So I sent the "login" command 0x7F and got the expected 0x79 reply (ACK). Good! The MCU is in the booloader! Then I sent a Get command (0x00 0xFF) and didn't get any reply. I sent the same command again and I got a NACK (0x1F) reply. These are the two only cases I can get alternatively. If a enter 0x7F, I get the same behaviour, the same two cases so it means the MCU didn't reset (otherwise 0x7F would enter in the bootloader again).
The behaviour I got with the STM Flash Loader demo matches the one I got with the serial tool: Once entering in the boot loader, commands don't work. May anybody tell me what's happening?
