Subject: [BUG] pxa3xx: wait time out when scanning for bb
Date: Tue, 28 Nov 2017 10:12:11 +0100 [thread overview]
Message-ID: <7df7abb5-e666-c999-e449-75762b551ea5@prevas.dk> (raw)
Hi Ezequiel
I'm currently in the process of doing bringup on a custom armada 38x board.
During the firsts boots of the Linux kernel we saw that the NAND driver
throws a lot of timeout messages.
Like this:
[ 28.321054] pxa3xx-nand f10d0000.flash: Wait time out!!!
[ 28.521054] pxa3xx-nand f10d0000.flash: Wait time out!!!
[ 28.721054] pxa3xx-nand f10d0000.flash: Wait time out!!!
That lead me to investigate the issue and found this thread (quite old):
https://www.spinics.net/lists/arm-kernel/msg488581.html
In the thread some is describing a possible race condition when the NAND
framework is scanning for bad blocks.
1. I tried enabling PREEMPT with no success.
2. I tried with commenting out the bad block scanning function, with
success but not very useful :-)
3. I enabled the BBT function in uboot and the kernel, and that
apparently fixes the problem.
Can we be sure not to see this issue/racecondition when we are up and
running? Is there any way to test this?
Br
Sean
