Hi,

We started to use SMT32F042K6 microcontroller. I need to download program via serial port. So I am tring to use flash loader demonstrator v2.6.0.First of all, I connected my board to PC via FTDI virtual com port device hardware in Boot mode. (115200br, 8bit, even, 1stop, no flow) I send &&sharp16;0x7F from a terminal program and I received 0x79 (ACK). I saw all bootloader commands which are describe AN3155 can be sent and received return messages.When I run flash loader demonstrator, it says ''target is readable, Please click the next to proceed.''. When I click the next button, I saw* Target combo box is empty* PID: 0445* BID: NA* Version: 3.1So I could not select MCU and I could not continue.I decided to use STMFlashLoader.exe from command line to deal with this problem. I sent ''STMFlashLoader.exe -c --pn 20 --br 115200 --db 8 --pr EVEN --sb 1 --ec OFF --co OFF --to 5000'' to set serial port. I received OK message.Then I sent,''STMFlashLoader.exe -i STM32F0_Low-density_32K''or ''STMFlashLoader.exe -i STM32F0_32K''everytime I receives ''Activating Device    [KO]No response from the target, Bootloader can not be started.Please, verify the bootmode configuration, reset your device then try again.Please, reset your device then press any key to continue.''When I run STMFlashLoader.exe in command line, I already checked serial port activity. The program (STMFlashLoader.exe) do not send any data via serial port until error message.How can I fix the problem? Is there any way boot the MCU via serial port? #bootloader #stm32f0-flash-loader

Hi,

I have the same problem with L0 controller series.The point is that FlashLoaderDemo 2.6 doesn`t support these new targets, because it wasn`t updated so far. If you look at map folder in FlashLoaderDemo there are map files for each type. You can see that map file for your device_id is not present there.I tried to make a map file by hand for my case. In principle this should work as soon as you write right addresses, paging scheme etc...I am in progress at the moment.
