43:25 renode boots up CP faster when disabling profiling
44:58 liking copilot and clangd
45:50 Renode prints CP message
46:15 Renode-run
48:28 Renode board definitions
49:10 sick of CMake
50:10 renode-run atmel - logging
52:30 Microptyon does both CMake and make files
53:18 Embedded.build
54:35 honcho ideas
55:20 back to renode logging
55:50 renode runmacro $reset
57:49 renode trace speedscope flamegraph visualizer
58:39 renode track memory use
59:20 poncho and api documentation
1:01:50 looking at the trace ( seen on show and tell )
1:04:20 would like to view characters sent to uart
1:06:20 perfetto.dev ( google tool )
1:11:30 serial delay PR 7041
1:20:20 using gdb to control profiling
1:21:22 how to get variable and uart monitoring into the profiling
1:22:30 back to PR 9207 and getting stuff to build
1:24:18 git switch back to squeeze_in_max
1:25:04 potential speed up of builds by sharing LTO
1:25:45 set config in tusb_config.h
1:26:30 Hazard3 + OrangeCrab / custom CP peripherals
1:28:00 Adafruit blog reference
1:30:55 model example github/tannewt/StemmaG0-Template ( nope - not this example )
1:34:12 Adafruit_CircuitPython_ULP_Blink (s2 and S3 coprocessor )
1:35:28 push changes for CI to process squeeze_in_max
1:36:42 (rant) makeqstrdefs.py uses concurrency
1:37:33 back to Adafruit_CircuitPython_ULP_Blink - clang ast generates python
1:44:45 seesaw doesn't load code over I2C
1:51:20 github/tannewt/embedded/tree/main/embedded
1:52:58 back to the build / pico w build errors
1:56:00 fix nordic port
1:59:00 commit the build error fixes
2:00:10 Nordic new chip announced - not out yet Cortex-M33 nRF54H20
2:02:15 also nRF54L15
