[U-Boot-Users] reading environment from flash fails
by Wolter Kamphuis 01 Dec '03

Hi all, I need some help converting a patch for ppcboot-1.1.6 to u-boot. I've got the following patch for ppcoot-1.1.6: http://wkamphuis.student.utwente.nl/u-boot/ppcboot-1_1_6_qs.patch This patch is for the QSLinux QST23/QS850/QS860T boards. See http://www.snmc.com/prod_qs850.html The patch is made by Daris Nevil (SNMC), it works fine but hasn't been ported to u-boot yet, it's also very large (+500k). The past few days I've been busy porting this patch to u-boot, version 1.0.0. While porting I've run into a problem. Saving the environment to flash ('saveenv') works but this environment isn't read when rebooting. I can't figure out why. Our board has 8Mb flash, mapped to ff800000. Here's the layout: ff800000 to ffee0000: root filesystem ffee0000 to ff000000: readwrite ext2 filesystem fff00000 to fff20000: u-boot fff20000 to ffffffff: linux kernel We define: #define CFG_MONITOR_BASE 0xFFF00000 #define CFG_ENV_SECT_SIZE (128*1024) #define CFG_ENV_SIZE (2*1024) #define CFG_ENV_ADDR (CFG_MONITOR_BASE + CFG_ENV_SECT_SIZE - CFG_ENV_SIZE) So the environment is located at fff1f800. I've added some debugging into the source, which results in: file console.c, func console_init_f, line 368 CFG_ENV_ADDR = 'fff1f800' gd->env_addr = 'fff08174' Memory location fff1f800 contains nothing, but after a 'saveenv' my environment is saved there. Memory location fff08174 contains my default environment and is unchanged after a 'saveenv'. Shouldn't gd->env_addr be equal to CFG_ENV_ADDR? Now my saved environment settings aren't read and after a reset all settings are restored to the defaults. The original patch, my unfinished patch and some screendumps are available on my website: http://wkamphuis.student.utwente.nl/u-boot/ Could someone give me a tip pointer where to look for a solution? I have a feeling it has something to do with the u-boot.lds file but I don't know what. thanks in advance, Wolter Kamphuis, MuLogic B.V.

[U-Boot-Users] [ANNOUNCEMENT] NIOS: more doc, rebuild board configuration
by Stephan Linz 01 Dec '03

01 Dec '03

Hi NIOS developers, yesterday I've finished my NIOS Development Kit comparison. As an result of it I've expand the NIOS documentation end rebuild the board configuration. The work is accessible by patches: (1) NIOS documentation ---------------------- http://prdownloads.sourceforge.net/cdk4nios/u-boot-20031125cvs-nios_doc.pat… In this patch you will find some more documentations: doc/README.nios supplementations doc/README.nios_DK Development Kit (DK) hardware overview doc/README.dk1c20_std32 NIOS CPU standard_32 at DK-1C20 doc/README.dk1s10_std32 NIOS CPU standard_32 at DK-1S10 doc/README.dk1s40_std32 NIOS CPU standard_32 at DK-1S10 doc/README.dk20k200_std32 NIOS CPU standard_32 at DK-20K200 doc/README.nios_CFG_NIOS_CPU config. reference for CFG_NIOS_CPU_ (2) LAN91C111 ------------- http://prdownloads.sourceforge.net/cdk4nios/u-boot-20031125cvs-smc91111_fix… Pending patch. We need it at NIOS platforms to avoid MAC setup failures. I'm not happy about the state of this patch ... (3) new DK1C20 configuration ---------------------------- http://prdownloads.sourceforge.net/cdk4nios/u-boot-20031125cvs-dk1c20_recon… main work: * moves DK1C20 board path from board/dk1c20 to board/altera/dk1c20 * makes a new common source path board/altera/common (at this time for flash access stuff only) * change/expand the Makefile * change/expand configuration file DK1C20.h Patch U-Boot and you can configure and make U-Boot for a standard_32 NIOS CPU at Altera's DK1C20. Type in: > make DK1C20_standard_32_config > make NOTE: make DK1C20_config works again and force the standard_32 configuration as default. (4) DK1S10 support ------------------ http://prdownloads.sourceforge.net/cdk4nios/u-boot-20031125cvs-dk1s10_suppo… Patch U-Boot and you can configure and make U-Boot for a standard_32 NIOS CPU at Altera's DK1S10. Type in: > make DK1C20_standard_32_config > make Any comments and notes to the new configuration framework are welcome. Scott, Patrice, what's your opinion ?
