There are 1 incomplete or pending task to finish installation of Semantic MediaWiki. An administrator or user with sufficient rights can complete it. This should be done before adding new data to avoid inconsistencies.When the device is in OPEN state, it is possible to access to the trace buffer located in a non-secure area of the SYSRAM, and analyse ROM code execution traces.
To analyze ROM code traces:
- copy the rom_trace_analyzer_py script below and paste it into a script file, in this example rom_trace_analyzer.py
- connect the debugger and use it to download SYSRAM address ranges [0x2ffc1c00-0x2ffC2400] in binary format into a file (for example traces.bin). The command below gives an example of how to this with "openocd" tool on a DK2 board.
openocd -f board/stm32mp15x_dk2.cfg -c 'init;cortex_a smp off;halt;dump_image traces.bin 0x2ffc1c00 2048;resume;shutdown'
- launch the following command:
python3 rom_trace_analyzer.py traces.bin
