Redboot does not boot up Linux properly
Last modified: 2011-05-24 17:24:03 UTC
There are times that Redboot fails to function properly and to load the Linux kernel from the UBI.
I analyzed the log for board bring up issue. Anytime that the Linux is run we function properly and the board boots up and runs squeezeplay as follows: vahidf@vahid_work:/tmp/logs$ cat ./baby3.TXT |grep -c "exec -c" 65 vahidf@vahid_work:/tmp/logs$ cat ./baby3.TXT |grep -c "Starting SqueezePlay" 65 vahidf@vahid_work:/tmp/logs$ cat ./baby3.TXT |grep -c "Squeezeplay 7.5.1 r8902" 65 However there are times that redboot starts but never runs the Linux kernel! vahidf@vahid_work:/tmp/logs$ cat ./baby3.TXT |grep -c "Platform: Logitech Bab" 71 From the logs in a normal run the redboot runs the following commands: RAM: 0x00000000-0x03f00000, [0x00095250-0x03ef1000] available FLASH: 0x00000000 - 0x8000000, 1024 blocks of 0x00020000 bytes each.

Unrecognized chip: 0xf8!!! hardware reset by POR It is clear that in failed cases the Redboot does not scan and detect the NAND flash bad blocks properly.
I can reproduce this problem by having an external battery connected to my Baby and taking the following steps: 1. Let the Baby come up with the external battery connected 2. Let it run for a while 3. Remove the AC 4. Have no activity on Baby. The Baby shuts itself down after 1/2 hour. 5. After this the system is supposed to stay in power off mode, but there are times that it tries to boot up and then this problem can happen.
I have not seen this problem with the latest MSP430 changes. I assume this bug is resolved.
Cannot reproduce with build r9443 on Radio. Going to close since problem identified and fix in place.
