Shkëmbime Linqesh – Trafik i Vërtetë Falas
Ç’kemi, Emri im është Sonila Cela, Do të doja t’ju sugjeroja një shkëmbim linqesh falas me lists.infradead.org ose çfarëdo faqeje tjetër që zotëroni. Mendoj se do t’ju pëlqejë të dini se kam në dorë një sërë projektesh cilësore, për të shkëmbyer linqe falas dhe jam i sigurt se mund të jetë frytdhënëse dhe produktive për të dy ne. Ju lutem më thoni nëse do të dini më shumë detaje, ose nëse keni sugjerime të mëtejshme për këtë çështje. Në pritje për të dëgjuar sërish nga ju!

[PATCH 06/10] bootsource: create arch independent bootsource framework
This patch seperates the imx independent from the arch independent code. The
following functions and enums are renamed:
- imx_bootsource() -> bootsource_get()
- imx_set_bootsource() -> bootsource_set()
- enum imx_bootsource -> enum bootsource

All correct in the code, so problem is not here. About DSS: I cannot help you with this CPU, but here is one point from OMAP4430TRM: "The main access to all DSS registers is through the L3 interconnect.

Overall, isn't it weird that DSS is offline (as indicated by IDLEST)? I suppose in ./arch/arm/mach-omap/omap4_clock.c this check: /* Check for DSS Clocks */ while ((__raw_readl(0x4A009100) & 0xF00) != 0xE00) ; should get extended to also check for correct IDLEST ...which would currently end in an endless loop :) Thanks -- Christoph ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox

malloc expects a pointer:
commands/mem.c:634: error: incompatible types when assigning to type
‘char[4096]’ from type ‘void *’
As you can see below, for a quick test I commented the lines, but
barebox still crashes.
Why don't you suppose that this is due to the non functional DSS?

I know getting the tools right for sending patches can be quite a high barrier sometimes. Most other Open Source projects will require the same if you want to participate, so I think it's really worth it to set this up, if it's not for barebox then it might be for the Kernel or whatever project you might be interested in. Most other people in your situation setup a Gmail account and end up sending mails from home if necessary until they can put enough pressure on their administrators. Sorry, I don't like loosing useful contributions, but on the other hand our workflow depends on being able to review and apply patches quickly.

[PATCH] ARM i.MX ESDCTL: Fix default enabled esdctl v2 controller
On some i.MX SoCs the SDRAM controller has chipselect 2 enabled
by reset default. This confuses our SDRAM size detection. We
already have a fix for this in place. This patch adds the fix
for i.MX35 which needs it aswell. Also since we now detect the
SDRAM size in the SoC specific entry functions we have to apply
the fixup there, too.

Here you register the driver only when usb boot is ready. It would be
better your register the device only when usb boot is ready. Are you
fine with this? Could you send a follow up patch?

Your patch is whitespace damaged, I won't be able to apply it.
As Jean-Christophe mentioned, you should use git-send-mail for sending
your patches. It does things just right.

The first thing you should check is whether your kernel is stored correctly on the NOR flash. try a: erase /dev/nor0 cp /someimage /dev/nor0 crc32 -f /someimage ls -l /someimage crc32 -f /dev/nor0 0+x (with x being the size of /someimage as output by ls -l) Sascha -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0| Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917- | ___ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
