Title: C860 Where's My D+m Menu Gone
Post by: louigi600 on January 13, 2007, 12:03:02 pm

After the recent installation of r121 on my C860 the D+M menu dissapeared.
Anyone have any ideas ?
There used to be an old issue, that should have been fixed, where the u-boot overwrote some other parts of the flash ... but that was before beta4 was released.
Well anyway rewriting /dev/mtd1 with the first 0x000dbfff of the orifinan nand backup image gets the D+M menu back ... probably there is still some overlapping stuff.

When you flash the new bootloader, it gets rid of that menu, which is in flashable space. Use Fn+D+M, which is in true ROM.

EDIT: Should have reread the post first. Sorry if my reply seems a bit off. Anyway, the FN+D+M menu is easier than fiddling with two bootloaders.

Hum ... that does not happen on my c760 and even with u-boot and r121 installed I stll can access the D+M menu.
You sure on this ... because also the C+D did not install u-boot correctly ... I hadto do a workaround for that too.

It appears that the D+M and Fn+D+M  have some difference (one is all black and one has a red label) on my c860 (but non on the c760) .... but I still think it's not a desired behaviour on the 860 as it works differently on my 760.
Since there is no difference between Fn+D+M and D+M on the 760 coud this mean that the diagnose menu is only on rom ... and that's why it does not behave badly after u-boot install ?

In any case I can confirm that Fn+D+M will get the diag menu up again with c860 + r121.
