Unable to attach to blackmagic using flipper build tool.
cnburke opened this issue · 4 comments
Hi. I'm trying to work my way through the flipper wifi dev board setup instructions, but I'm unable to attach to the running blackmagic process via USB or WiFi. My dev board seems to be working only if I manually compile blackmagic myself and use the idf.py tool to build and monitor. I have tried every combination of serial port and boot mode the instructions offered, as well as trying the WiFi direct and direct USB methods. If anyone could let me know if I'm doing something stupid here, I'd greatly appreciate it.
The log at the end is taken from flipper's VS Code Debug configuration with the "showDevDebugOutput": "raw" option uncommented.
I'm running ./fbt flash_blackmagic BLACKMAGIC=/dev/cu.usbmodem01 before attempting to debug.
I am able to achieve monitoring via
➜ blackmagic-esp32-s2 git:(dev) ✗ idf.py -p /dev/cu.usbmodem01 monitor
Executing action: monitor
Running idf_monitor in directory /Users/cameron/code-projects/flipper/blackmagic-esp32-s2

--- idf_monitor on /dev/cu.usbmodem01 115200 ---
--- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H ---
If it helps, in my attempts, I have seen the error of "'monitor' command not supported on this target" (or something along those lines, pulling from memory as I can't get the device back into whatever state this was).

Having the same issues... will post if I find a solution
saw a few posts looking into this and most of them were flavors of "check wiring" well its not quite wiring but...
On flipper:
settings->system->debug ON
Same problem here, any idea?
