Subject: resetting m25p80 on reboot
Date: Thu, 09 Jul 2015 07:59:06 +0200 [thread overview]
Message-ID: <559E0DAA.20105@openwrt.org> (raw)
Hi,
there are some SoCs made by MTK/Ralink, where the bootrom has problems
when the flash chip has 4 byte addressing enabled. This will make the
unit not boot properly after reboot was called. The flash chip needs a
reset prior to working. Paul has sent a patch to our ML which looks good
to me but i wanted someone that knows more about m25p80 to look at it
before i merge it into OpenWrt and send it upstream to linux-mtd
the patch in question can be found here
-> http://patchwork.ozlabs.org/patch/492878/
I am not subscribed to linux-mtd so please CC me on replies.
thanks in advance,
John
