December 7, 2022 update:
- Code describe below (moved to branch v0.5_merge_request_15) is deprecated.
- Current v0.7 code at https://sourceforge.net/p/stm32flash/code/ci/master/tree/ supports "-b 0" flag with same functionality as branch's "-N".
- This GitHub repo's master branch updated to current v0.7 (commit [553016] as of this date/time), but does not have full git commit history and may become out-of-date.
- Please instead use most recent v0.7 (or later) from SourceForge repo, or equivalent distro binaries.
Fork of https://sourceforge.net/p/stm32flash/code/ci/master/tree/
- minor enhancement to upstream code ...
- to add support for opening
/dev/pts/<N>pty (pseudo-tty) device special files ... - created by buck50.py ...
- connected to a "Blue Pill" STM32F103 USB device running buck50 firmware ...
- connected via UART TX/RX to device being flashed ...
- because pty device files do not support changing baud rate, parity, bit size, stop bits, etc. ...
- as commanded by
stm32flashviatcsetattr()library calls ... - thus
stm32flashexits with error.
Fork checks for "/dev/pts/" in stm32flash [tty_device] commandline argument and bypasses the tcsetattr() call. Also adds explicit -N commandline to force bypass regardless of [tty_device] name.
When used with buck50 firmware, baud rate, etc. must be set via the buck50.py user interface prior to invoking stm32flash.
