I'm editing this as my work today (4/9/2022) has yielded progress but led me to a specific problem preventing me from using the tool.

The problem I'm encountering is unable to flash device - the STLINK device itself is being detected, and it can detect the target device properly (chip ID 0x412), however, the two errors below tell me that st-flash may not be performing the task required of it.

I populated /usr/local/stlink/chips (which was not installed when I installed 1.7.0 .deb package) by copying the /chips/ directory to /usr/local/stlink/chips.

The target is STM32F103C6T6 low-density type (0x412), 32K flash, and is being correctly identified.

Below are sessions where I have attempted to erase the target device, and then attempted to read back from the target device (expecting erased flash, FF bytes.) I removed the prefix characters from comment lines in the chips file as this was interacting with HTML.

st-flash erase yields "Failed to parse flash type or unrecognized flash type" and does not appear to run.
