[U-Boot-Users] [PATCH] RTC: Fix month offset by one problem in M41T62 RTC driver
by Stefan Roese 03 May '08

This patch fixes a problem with the month being read and written incorrectly (offset by one). This only gets visible by also using the Linux driver (rtc-m41t80). Tested on AMCC Canyonlands.

Hi Sascha, This is with regards to U-Boot V2 .dox files. Are these hand coded or was some WYSIWYG editor generated? E.g.: http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot/u-boot-v2.git;a=blob;f=Docum… Thanks and regards, Nishanth Menon

[U-Boot-Users] Configuring U-Boot for MPC8349E in little endian mode
by vivek.trivedi＠wipro.com 02 May '08

02 May '08

Hi, We are using MPC8349E based board in big endian mode. It is working fine with U-Boot 1.1.3 . Now due to some reason we have to configure 8349E in little endian mode. I have modified RCW, HID2 and MSR registers for this and built the U-Boot with -mlittle-endian(gcc 3.4.3) and -EL (ld option ). Now code is starting properly in Start.S but it is jumping to alignment vector(0x600) whenever it hits a branch instruction(b , bl). Then it stops at 0x63F in alignment exception vector handler. Has any one tried configuring U-Boot for MPC8349E in little endian mode ...? We have also tried to build U-Boot with -mstrict-align option, but it has not helped us. Are we missing any alignment option in gcc for compiling U-Boot. Any help will be appreciated. Thanks, Vivek Trivedi

Hi All I have been working with tftpboot and the kernel used to boot. I am trying to make a standalone image. Initially I am keeping rfs on network and just copying the uImage in dataflash using an emulator. But I get an error "IP-Config: Failed to open eth0". Any imputs on this?

[U-Boot-Users] question about running uboot on armulator
by loody 02 May '08

02 May '08

Dear all: I try to run uboot, configed as smdk2410, on armulator, compatible as ARM7TDMI, but I receive "undefined instructions" exception while running the code "bl cpu_init_crit" in start.S. The ISA of both smk2410 and arm920t is V4T and bl is the instruction that already supported form V1. Does the error come from my using armulator? But this instruction seems have nothing about HW, could someone tell me where I got wrong? Appreciate your help, miloody

[U-Boot-Users] Memory Size issue @ MPC83xx
by André Schwarz 02 May '08

02 May '08

All, my MPC8343 based system is running fine, but I'm not able to use more than 256MB of memory. Is this a general or known issue ? I'm not quite sure where the problem is since u-boot *seems* to be running fine. Situation : - 2 Micron 16-Bit (2 GBits each) chips soldered down on the board giving 512MByte total. - Connected to CS0 @ 32-Bit memory bus. - memory size defined and recognized correctly - set up CS0_BNDS for 512MB - set up BAT0 + BAT7 for mapping (a single BAT is limited to 256MB). - configure cpu to use high BATs by setting HBE bit in CFG_HID2. - dtb memory size set up correctly and "mtest" works all day from 16M to 500M .... Booting a 2.6.25 kernel crashes during dtb parsing. Limiting memory size to 256MB and skipping BAT7 gives a running system. At first glance this looks like a topic for the linuxppc list. But it *could* also be a u-boot related issue ... Any help is welcome ! regards, André Schwarz MATRIX VISION GmbH, Talstraße 16, DE-71570 Oppenweiler - Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschäftsführer: Gerhard Thullner, Werner Armingeon, Uwe Furtner
