I hacked up some scripts for debugging of the PHY transmission errors. It consists of two parts. One patch that has to be applied to the kernel driver (latest wireless-testing!) and one firmware binary patcher script (for latest supported firmware only!) Both are included in the attached tarball. Extract the tarball. So you first have to apply the included "b43-kernel-patch.patch" to the kernel driver and recompile your kernel. Then you have to patch your firmware by doing: cd phyerr-patcher-001 bash ./patch-phyerr-logger.sh /lib/firmware/b43/ucode5.fw You might have to adjust the path to your firmware. On successful patching, the script will exit with a nice smilie: :) So when running the modified driver with the patched firmware, it should dump the shared memory every time a PHY error occurs. More state dumps can be added to the kernel driver. The firmware is halted while the phyerr logger function is running, so state should be consistent. WARNING: This patch might kill your cat, or at least disturb your wireless connectivity. Only use it for debugging the PHY transmission errors. Note that these scripts require a complete compiler toolchain, including flex and bison, on your machine, as it will compile the assembler and disassembler tools. -- Greetings Michael.
