Re: [INFO] Developers chat (was "Slack ChibiOS workspace")

Hi, So far we are using a single Telegram channel, it is sufficient for a limited number of persons and it is working very well, lots of problems are solved quickly. Since the number is increasing we will probably switch to a more structured environment later on and we may go back to the suggested s...

Re: [DEV] STM32MP1xx support
