Hello all,
I am moving from bdiPro to bdiGDB and am having a difficult time getting the bdi2000 working with my mcp8266ads-pci board. I had thought that the mpc8260 cfg file would have been sufficient to accomplish this:
MPC8260>prog 0xfff00000 /tftpboot/u-boot.srec srec Programming /tftpboot/u-boot.srec , please wait .... Programming flash passed MPC8260>verify 0xfff00000 /tftpboot/u-boot.srec srec Verifying /tftpboot/u-boot.srec , please wait .... Verifying target memory passed
But then I do a reset, and a "go", but see nothing on the serial console.
MPC8260>reset - TARGET: processing user reset request - BDI asserts HRESET - Reset JTAG controller passed - Bypass check: 0x55 => 0xAA - Bypass check: 0x55 => 0xAA - JTAG exists check passed - Target PVR is 0x80911014 - COP status is 0x01 - Check running state passed - BDI scans COP freeze command - BDI removes HRESET - COP status is 0x05 - Check stopped state passed - Check LSRL length passed - BDI sets breakpoint at 0xFFF00100 - BDI resumes program execution - Waiting for target stop passed - TARGET: Target PVR is 0x80911014 - TARGET: resetting target passed - TARGET: processing target startup .... - TARGET: processing target startup passed MPC8260>go - TARGET: target has entered debug mode
I am using the same u-boot that I compiled for use with bdiPro, so I am pretty sure that it works for the board - I have been using it for some time.
I am very new to hardware programming, so please bear with me if I am missing the painfully obvious.
Incidentally, the reason I had to switch from bdiPro was that during kernel testing, u-boot stopped working after a boot - at which point tried to re-flash and this failed - it turned out that somehow flash sector 27 had becomed locked, and there was no way to unlock it from bdiPro; thus subsequent attempts to flash the board would fail.
Now that I am using bdiGDB, I would like not to have to switch between the 2 to accomplish different tasks ( obviously ), and I very much like the idea of having an alternative to printk's to conduct kernel debugging ( how I got in this mess in the first place).
Again, thank you very much for any assistance.
Currie
