[U-Boot-Users] how to take off CONFIG_S3C2410 setting
by loody 13 May '08

13 May '08

Dear all: I try to build make smdk2410_config without CONFIG_S3C2410 define. I see the include path is BUILD_DIR/include, BUILD_DIR/include2 and uboot/include. I have set CONFIG_S3C2410=0 in include/configs/smdk2410.h and also check it as 0 in autoconf.mk, too. But the final image I build still run through the region that defined as CONFIG_S3C2410 =1. Would someone tell me where I need to check or I miss something? appreciate your help, miloody

[U-Boot-Users] Debug u-boot with SAM-ICE/J-link
by Norman Cheung 13 May '08

13 May '08

I would like to know what is the quickest way to set up Atmel's SAM-ICE with the AT91SAM9260EK board to run GDB? My preference is to run under a linux host, but I can run under Windows if that is easier to setup. Any ideas, suggestions or experiences. Thanks, Norman

[U-Boot-Users] U-Boot v1.3.3 release
by Wolfgang Denk 13 May '08

13 May '08

Hi everybody, because we had to do some non-trivial last-minute changes to U-Boot (like backing out a couple of problematic commits) I felt we need a little more time to test the current code again. Beause of that I decided to post-pone the release of v1.3.3 by a week (or less, if we feel confident). See http://www.denx.de/wiki/UBoot/ReleaseCycle Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de "It ain't so much the things we don't know that get us in trouble.

[U-Boot-Users] SMSC LAN8700 and LAN8187
by Kevin Greer 13 May '08

13 May '08

Hello, Does anyone know if u-boot will work with the SMSC LAN8700 (same interface as LAN8187) Ethernet transceiver? Specifically I am trying to use it with the Atmel AT91SAM9260 microcontroller using MII. I am developing a board similar to the AT91SAM9260-EK evaluation kit and would like to replace the Davicom DM9161a. If u-boot currently doesn't work with the LAN8700 can anyone provide me with a little guidance as to the magnitude of the effort to add this transceiver to u-boot? Sorry if my question is a bit naive, I am a newbie when it comes to u-boot. Thanks, Kevin

[U-Boot-Users] [PATCH 2/4 V3] PPC: Change lib_ppc/bat_rw.c to use high bats
