Hi,
genromfs 0.5.1 is ancient, this has already been fixed in 0.5.2 several
years ago, together with a few other improvements.

Hi,
a driver for the ADS7846 is in the 2.6 kernel already, and there are
patches available for ADS7843 support.

the PIC32 top model has 128KB SRAM and 512KB flash. It doesn't seem to
have an external bus. I heard those rumors about Linux too, seems to be

Hi,
of course you can add your own entry, you just need to know the erase
sectors of your flash. The preferred way is to use CFI, if your flash
supports that, however. I think that the missing jedec_probe entry isn't
the real problem in your case, since the manufacturer/device id from
your log do

for NOR flash, the number of erase cycles on each sector is limited, not
the number of writes. For the flash lifetime, it doesn't make a
difference if you write one byte at a time or a complete sector at once.

I have always installed elf2flt in a slightly different way. Instead of
replacing ld,
I install the ld-elf2flt shellscript as "real-ld". collect2 will look for
real-ld before

most probably, at least one of your object files/libraries has been
compiled with the -fpic option. You have to fix that, overriding the
flag with flthdr doesn't work. Do you have a special reason why you want
to build busybox without xip? You know that the large text segment of
busybox is allocat

I had uClinux running on a W90N740 based router with only 1MB Flash and

take a look at "stackcheck":
http://cvs.home.at/midori/sources/debugtools/src/
It will show a ps-like list of all processes, together with the free
amount of stack. The application should work on all platforms. It
requires two small kernel patches. I have used it with the 2.4 kernel.

Have you used the ld script for xip? You have to replace
vmlinux-armv.lds.in by vmlinux-armv-rom.lds.in.
For the final image, you have to create seperate text and data images,
you can see that in many vendor makefiles how its done.

all creates the linux.data
image, with text sections removed. Finally, they are cat'd together to
create the flash image. Take a look into the vendor directories, there
are lots of Makefiles as an example.

XIP isn't necessarily for flash o

are you talking about kernel or userspace? For the kernel, take a look

Hi,
there are a few problems:
- you are using the blkmem driver in addition to MTD, are you aware that
you have to assign different major device numbers to blkmem and mtd?
- the kernel can't detect your flash. I don't know about your hardware,
but you have to specify the base address of the flash
Hi,
if you need 2.4.34, it is in the latest uClinux-dist test distribution:
http://www.uclinux.org/pub/uClinux/dist/uClinux-dist-test-20080109.tar.bz2
Eventually, your download is corrupted by some crappy browser, you can
use curl for download instead.
Regards,
Erwin

you can use uClinux-dist with Atmel/AT91. You will nead a minimum of
~2MB ram on your board.
