This is best done with the "serial - port mod" described on the home page, along with a serial port converter - for the 3V signals from the Jukebox. - -2) Build or download a GDB SH1 cross debugger - -3) Compile the GDB stub from the CVS "gdb" archive - For Player models, just type: - # make - - For Recorder, type - #make RECORDER=1 - -4) Copy the newly built ARCHOS.MOD to the Jukebox. - -5) Start the Jukebox and fire up the GDB with the elf file you want to debug - as an argument along with the baud rate: - - For Player: - # sh-elf-gdb -b 38400 test.elf - - For Recorder: - # sh-elf-gdb -b 115200 test.elf - -6) In GDB, type: - - (gdb) target remote /dev/ttyS0 - - /dev/ttyS0 is the serial port you want to use. I guess Windows users - would type COM1 or something like that. - - GDB should answer with a message like: - - Remote debugging using /dev/ttyS0 - 0x090014b6 in ?? () - (gdb) - -7) Load the code from the elf file you specified on the command line: - - (gdb) load - - GDB should answer like this: - - Loading section .text, size 0x6b00 lma 0x9018000 - Loading section .data, size 0x738 lma 0x901eb00 - Start address 0x9018290, load size 29240 - Transfer rate: 11696 bits/sec, 102 bytes/write. - (gdb) - -8) You're set. Now try to set a breakpoint and run: - - (gdb) b main - Breakpoint 1 at 0x9011b2a: file main.c, line 192. - (gdb) c - Continuing. - - Breakpoint 1, main () at main.c:192 - 192 app_main(); - (gdb) - - Good luck! - - -Technical details: - - As for now, the GDB stub occupies the memory from 0x900000 up to - 0x9018000. - - Compile and link your test program at 0x9018000 and up, and it will work. - - The baud rate is 38400 for Player, 115200 for Recorder, and the settings - are 8N1. - - Note that you may have to change the ATA I/O address in the ATA_CONTROL - macro in sh-stub.c. go to Menu->Debug (keep out)->View HW info to find out. - - Linus Nielsen Feltzing |
