I for one second this patch. I have just bricked my router trying to get the current trx image to work on my WNR3500L. I am not sure why it worked previously but it does not now, but it was doing just as described, hanging at Starting program at 0x80001000. I thought it was because the MTD command had failed, so I tried from CFE and inadvertently overwrote my CFE - doh!

The thing that makes my blood boil is this - there are plenty of use cases where initramfs is a must: - ELF boot from external media - KEXEC to external media - TFTP boot None of these currently work in BB whereas they used to. And you cannot easily add the scripts to support them because all the 'hookability' is outside of process id 1. This means when you try switch_root it blows up in your face. If you try pivot_root it fails cause you can't pivot_root ramfs. I have raised a bug - but no response yet. I have also submitted a small patch which was bounced?

[OpenWrt-Devel] [PATCH] [boot] /init: allow easier customisation of ramfs boot.
/init is the first pid 1 process in an initramfs environment. This fix adds lines to check for the existence of /bin/ramfsinit or /sbin/ramfsinit and exec if present. This allows packages to switch root early in the boot process. This will help support booting or kexecing from external storage and go some way toward fixing ticket #17465.

[OpenWrt-Devel] AsiaRF MT7620a mounting sdhci drive readonly
Hello All,
Been trying to get an AsiaRF based MT7620a board running using CC r42230 and
having issue getting the MMC SD card reader
to mount rw.
I have been in communication with the manufacturer to discover the GPIO (if
any) used for the WP line for the SDHCI card
reader on the board. They have not gotten back to me. In the mean time I have
attempted to use some of the mmc driver
properties such as wp-inverted to no avail. In desperation I implemented a
patch based on
http://permalink.gmane.org/gmane.linux.kernel.mmc/25615
which tells the driver to ignore the write protect line and assume r/w
always... yet the card still mounts read only.
note that when mounting the same SD card using a USB based reader the file
system mounts rw as expected.
here is the mount table showing the ro mount
root@OpenWRT:~# mount
rootfs on / type rootfs (rw)
snip...
/dev/mmcblk0p2 on /wxa type ext4 (ro,relatime,data=ordered)
here is the DTS definition for the board
sdhci@1013 {
status = okay;
broken-wp;
};
following is the patch (some of you might find it useful). Any thoughts would
greatly be appreciated.
