[U-Boot-Users] looking for 8266.cfg file

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.

- 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
- 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

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.
