I need the mfr. ID at 0x4f and it is two bytes, you need to do the high byte switch. If you are feeling brave, please do: prog/dump/i2cdump 0 0x2d #high byte dump prog/dump/i2cset 0 0x2d 0x4e 0 #set low byte prog/dump/i2cdump 0 0x2d #low byte dump prog/dump/i2cset 0 0x2d 0x4e 0x80 #back to high byte We want to see if the Vendor ID register at 0x4f changes when you switch the high/low access. And does it change any other time. If that really is a ID register then I can recognize it. gerard at linuxfromscratch.org wrote: > > I didn't see an option to add more info to a ticket. > > Anyway, here's what one of you guys wrote: > > Reply from support: > > The perl warnings aren?t the problem. > You have some chip we don?t support.
