Hello.
The latest Appro IPNC Beta 2.8.0 (PSP 04.04.00.01) includes the NAND ECC change to running BCH8 on both u-boot and Linux. This runs okay, but occasionally (~every 20 minutes) spits out the following:
Read of newly-erased block at <block address> failed: -74. Putting on bad_list
JFFS2: marking eraseblock at <block address> as bad
I have looked at the flash content and it looks fine to me. Occasionally, the OOB data will not be totally cleared, but I don't know if that is valid or not.
I can continue with development for now, but eventually I'm going to be out of flash blocks (which aren't bad). I see this with both the Mistral 8148 EVM and my custom 8148 board (using the same NAND part). Both boards work fine with the previous PSP/linux version.
What's going wrong here?
Thanks,
Christopher
