[U-Boot] Meaning of CONFIG_SYS_BOOTMAPSZ/cns3xxx port to v2009.01
by Christoph König 01 Apr '11

01 Apr '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello list, we want to use the tftp update functionality of u-boot to easily maintain our access points. We have the Gateworks' Laguna board with a Cavium cns3xxx SoC chip on it and a delivered u-boot v2008.10. For this, there are also the (extended) sources provided (see http://svn.gateworks.com/bsp/laguna/trunk/u-boot-2008.10). But; the automatic tftp update comes with version 2009.01... So, at first I diffed the Gateworks' v2008.09 against v2008.09, rebased it to v2009.01 and fixed the conflicts (if someone is interested, I can provide a patch for v2009.01). Rebasing against v2011.03 produces a lot of conflicts, which I can't fix (because I run out of knowledge, what happens in the code). If I now enable the CONFIG_UPDATE_TFTP flag (and LIB/LIBFDT), I got a missing CONFIG_SYS_BOOTMAPSZ. Ok, that's not so hard- I just defined it to a value (8<<20) to see if it's working- and yes it's compiling and working on the board. But how can I get the right value for it? In the background, I use the openwrt-trunk with uLibc 0.9.32 for crosscompiling.

Yes, indeed. Unnesting means to move the inner struct declaration outside, like that: struct ftsmc020_bank { unsigned int cr; unsigned int tpr; }; struct ftsmc020 { struct ftsmc020_bank bank[4]; unsigned int pad[8]; unsigned int ssr; }; > > Again: if you need larger numbers of such entries you are doing > > something fundamentally wrong.

We take care to provide global data and an initial stack very, very early in the initialization sequence. You canuse C code long before you can access the system RAM. > Hence assembly code to setting SMC and PMU in lowlevel_init is a necessity I seriously doubt that. Just because many boards are writen that way does not mean that's how it must be done - actualy many just copied existing bad examples without thinking.

[U-Boot] Saving environment question
by Charles Krinke 01 Apr '11

01 Apr '11

I have an MPC8323ERDB that I am trying to update from an older version of u-boot to 2010.12 and am having trouble saving the environment with "saveenv". I turn on the debug in env_flash.c and can see the failure is at line 271 near the beginning of the saveenv() routine where we are trying to mallic(up_data). up_data = (end_addr + 1 - ((long)flash_addr + CONFIG_ENV_SIZE)); debug("2 Data to save 0x%lx end:%lx new:%lx\n", up_data, end_addr, flash_addr); if (up_data) { if ((saved_data = malloc(up_data)) == NULL) { printf("Unable to save the rest of sector (%ld)\n", up_data); goto done; } At the debug statement, up_data = 0x1E000, end_addr = 0xFE07FFFF and flash_addr = 0xFE060000. The end_addr and flash_addr seem reasonable to me as the flash in 128Kb sectors in the MPC8323ERDB so the first few sectors are: FE000000 - FE01FFFF FE020000 - FE03FFFF FE040000 - FE05FFFF *FE060000 - FE07FFFF* The malloc itself appears to be failing and this puzzles me. Would anyone be willing to point out the location of the "naievety hole" I have fallen into with this little sub-project?? -- Charles Krinke
