So JTAG'ing is done. I am back to the state I was before with mostly LB9A firmware and latest ONIE 18.09L u-boot but configured with old firmware u-boot-env. I have replaced the software image on the NOR flash filesystem with LB9 software. I have a 2.6.35 Kernel for LB9A and I have been attempting to merge the LB9 ONIE device tree with LB9A device tree and I have been able to get the enet working again when booted to Linux but there appears to be no driver for /dev/i2cDev which is number 242. I am not sure if this kernel from the LB9A has all the same pieces are not but the switch fabric does seem to initialize and appears to act like a basic switch. Fans will not slow and I fear that modifications to switch fabric will fail as the output on the screen is constantly complaining that it can not write to /dev/i2cDev. At this point I am not sure that device tree is correct or the kernel from LB9A will work on this switch.
If anyone with an older Quanta LB9 switch would be willing to help. I need the NOR Flash dump from an LB9 running QNOS2 and it is easy to get but slow.
Connect serial port to switch.
Stop the boot process by hitting spacebar at the count down prompt of u-boot.
Turn on serial port logging (every app is different but easy in TeraTerm)
run command 'printenv'
run command 'md.l 0xFC000000 0x00800000' <- this command will take a while at 115200 serial baud rate
Save log output, gzip, and send to me.
This would be a great help in getting my switch back up and working.
Thanks
