[U-Boot] uboot loading address.
by Rajesh Venkataraman 26 Nov '08

26 Nov '08

Hi, I want to know about the U-BOOT loading address in MPC8572DS development board (boot flash Address map 0_F800_0000 to 0_FFFF_FFFF -> 128Mb). For MPC8572 the default boot rom address is 0xff800000, I also want to know to which address I have to load the uboot first and once uboot gets executed where I have to store the image in the same flash area (possibly the image storing address) if down load the image via tftp. Can anyone help me on this.

[U-Boot] Newbie problem, all commands become unknown if I call a function
by Jon Povey 26 Nov '08

26 Nov '08

"Hi, I am having problems..." I am trying to modify u-boot to call my custom function to decide whether to silence the console or allow it, by calculating the SHA-1 hash of an environment variable (password-based dev console). If my function is called, it succeeds, but all commandline comands report Unknown command, including "nboot" and "boot" which are part of the bootcmd. My function source is in the /boards/myboard directory and called at the start of console_init_r() (I hacked a relative #include at the top of console.c) I guess I am not understanding something like jump tables or memory/stack limits, and corrupting something. To put as many people off as possible, I am starting with sources from Texas Instruments for the Davinci DM355 (ARM core), which is apparently based on u-boot 1.2.0. On this platform u-boot is loaded into DRAM from NAND flash by a separate first-stage loader. I know this is nothing like the current u-boot version and don't expect anyone to spend much effort trying to support me, but I hoped someone might be able to say "ah yes, that sounds like you've simply xyz, you need to abc in your function" or point me at some relevant information. Some example console output showing the failure: --- this is MT29F16G08FAA device UBL: detected valid U-Boot magic number UBL: booting to U-Boot U-Boot 1.2.0 (Nov 26 2008 - 10:25:47) DRAM: 128 MB NAND: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron NAND 1GiB 3,3V 8-bit) Bad block table found at page 524224, version 0x01 Bad block table found at page 524160, version 0x01 nand_read_bbt: Bad block at 0x02420000 nand_read_bbt: Bad block at 0x02480000 nand_read_bbt: Bad block at 0x025c0000 NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron NAND 1GiB 3,3V 8-bit) Bad block table found at page 524224, version 0x01 Bad block table found at page 524160, version 0x01 nand_read_bbt: Bad block at 0x0aa80000 2048 MiB Hashes matched - allow console In: serial Out: serial Err: serial ARM Clock :- 216MHz DDR Clock :- 171MHz Hit any key to stop autoboot: 0 Unknown command 'dhcp' - try 'help' Unknown command 'setenv' - try 'help' Unknown command 'tftp' - try 'help' Unknown command 'bootm' - try 'help' myboard # -- Jon Povey, Design Engineer jon.povey(a)racelogic.co.uk | +44(0)1280 825983 Racelogic is a limited company registered in England.

[U-Boot] New board
by Ing.G.Morandi (Portatile) 25 Nov '08

25 Nov '08

Hello, we are currently developing a board based on AT91SAM9G20 on a mini-pci form factor. We'd like to distribute all the documents (i.e. schematics, bom, gerber, etc.) freeware as well as all the patches of u-boot and linux in order to have this board included into the main trees. My questions are: 1) do we need any authorization or registration to do this? 2) what other requirements shall we respect to be included into the main trees (u-boot and linux)? Best regards Gianfranco

Re: [U-Boot] [PATCH v3] mpc83xx: New board support SIMPC8313

In response to my own email: > I did not see this when I built before submitting my patch. It seems to build > fine using ELDK version 4.1. I just tried building with 4.2 and am > seeing the errors that you described. For some reason, the 4.2 build has > about 48 extra bytes to it, and is once again putting me over the 4K > bootstrap limit. I'm going to look into getting the size down, but that's a > decent number of bytes to try to optimize out. I've been trying to trim down my nand_spl bootstrap so that it will be below the 4K limit allowed by the processor. However this is proving to be very challenging. I have noticed that there is a little over 100 (decimal) bytes that are being unused at the beginning of the resulting binary (after the HRCW and version string). Would it be possible to move some functions in start.S (mpc83xx) in front of this (see below) part of the code? . = EXC_OFF_SYS_RESET .globl _start This would allow for more board specific nand_spl boot code. Would something like this be allowed or am I barking up the wrong tree? Ron

Hi Yasushi and others, I am going to redesign microblaze u-boot branch to similar style as is xilinx ppc platform and I would like to remove suzaku board too because I don't have any info if someone use it. Is someone who use this board? Thanks, Michal -- Michal Simek, Ing. (M.Eng) w: www.monstr.eu p: +42-0-721842854
