Hi. [[BR]]
We were using OLPC ext3 build 395 image to boot to system , and it can
work just after "flash_eraseall -j /dev/mtd0" with '''B2''' boards
including previous stage boards. [[BR]]
But it seems not to work well with '''Pre-B3''' boards. [[BR]]
In addition , B2 and PreB3 testing boards were using same BIOS version
(Q2C09) at that time. [[BR]]
So we are confused with that situation. But if it is normal , we might
ignore the issue.[[BR]] [[BR]]
Besides , because some procedures are needed at CL1 Manufacturing
Stage.[[BR]]
First , we need booting to system by manufactring USB Key (or from
network). [[BR]]
Second , we need to erase/format Nand Flash and mount MTD device
(/dev/mtdblock0). [[BR]]
Then , we will copy our manufacturing test programs into NAND Flash for
testing and verifying system in each manufacturing procedure. [[BR]][[BR]]
Best Regards,[[BR]]
