[U-Boot-Users] static function pointers and reallocation
by Mattias Bostrom 02 Nov '07

02 Nov '07

Hi, We have a custom board based on Lite5200B and started our development from Freescales BSP including U-Boot 1.1.5. I have now added a U-Boot command that includes code from an earlier project. In that code there is a static vector declared at file scope with function pointers in it. When I recieve data via CAN I look up which function to start and uses the function pointer in the vector. Since the function pointers are set at compile time they point to flash memory and execution jumps to flash. Is that as expected or? In binaries for ARM the linker has made all the reallocation. In my binary all adresses are in flash. I thought this would magically change after reallocation and my function pointer should point to the new ram adress. Do I need to do something special to get my function pointers to point to ram? Or do I have to initialize the vector with function pointers in runtime to get the correct adress? I guess the GOT has something to do with this but I'm not very good at assembler so I'm not sure what happens. Is there a "best practice" for function pointers and U-Boot? We're using gcc 4.1.1 and glibc 2.3.8. Regards, Mattias Bostrom Hur träffade du din kärlek? Skicka in er historia och vinn biobiljetter. http://www.spraydate.se

[U-Boot-Users] MTD update?
by William Juul 02 Nov '07

02 Nov '07

On two custom designs (ARM and PPC based) we are running YAFFS on NAND devices in U-boot and Linux. We had problems configuring YAFFS/MTD in such a way that we could use the same partition in both U-boot and Linux. Additionaly we could not find support for 4KB pages in the current MTD implementation in U-boot. We also ran into (easily fixable) problems since nand_ids.c contained two entries with the same ID. Thus, we upgraded the MTD files in U-boot by using the corresponding files in Linux 2.6.22.1, which we used at the time). This was a rather large change of u-boot source, but it solved all problems we had with NAND. The patch touched several files in drivers/nand, include, include/linux, include/linux/mtd and common. The patch has a total size of >300KB. Currently this patch is based on 1.2.0 and it will require some work before we submit a patch: - base the patch on 1.3.0 - MAKEALL ppc/arm is currently breaking for some configurations - some code clean-up We do not have the resources (time/HW) to test this patch on anything else than our two custom boards. Thus we will have to rely on help from the community after submitting the patch.. Comments?

[U-Boot-Users] [PATCH 4/4] PPC4xx: Add support for Korat PPC440EPx board
by Larry Johnson 02 Nov '07

02 Nov '07

These patches add support for the PPC440EPx-based "Korat" board to U-Boot. They are based primarily on the Sequoia board support.
