Re: [U-Boot] Q: NAND read/write: unaligned offset
When using nand_write_skip_bad, the aligned offset refers to page (not sector or block), so if as I understand , I can read from the start of page the whole relevant data, then modify only the parts which is changed, That's not the same thing as just filling in the parts you're not writing with 0xFFs, but still it's not safe unless you erase the block. Even if the main portion of the page doesn't contain any bits that go from 0 to 1, and you've got the data to calculate the proper new ECC, the ECC itself will probably have bits going from 0 to 1. Plus, some chips may not take writing 0xFFs as a no-op -- see the recent patches to support skipping pages with all 0xFFs on write. -Scott I wanted to write different parts of the page each time. And now I undertsand that the ECC is stored for each page, which mean that what I am trying to do , is impossible (if I am using ecc), i.e. writing the same page without erasing is not allowed when using ecc. Am I right about this conclusion ? Thanks, Ran ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

I am experiencing the same problem with SATA right now with v2011.06-rc2 (tried also the latest master). If MVSATA_STATUS_TIMEOUT in mvsata_ide_initialize_port is ignored, SATA drive is found on the second port and I am able to read the drive's content. Inspired by what you say about timeouts, I thought perhaps increasing the timeout from 10ms to 1s might make a difference -- that worked! ... except that now, it's working regardless :-( So, I've no idea if that's really related to what's going on, because I've now gone as far as reducing the timeout to 5ms and it's _still_ working fine, so perhaps some part of the SATA subsystem was in a state that was somehow reset by waiting a bit longer for the startup once, and that's somehow fixed it. It is still working despite powering down the machine for a while, so I'm guessing whatever changed is something to do with the state of the hard drive. Sadly that means that I've now lost the ability to test this, since trying any of the versions that were previously failing now work. Anyway, Alexei, try increasing the timeout (i.e. the value being assigned to timeleft) --- if that works for you too, it seems pretty harmless, so might be appropriate for wider adoption. I have already tried longer timeouts for timeleft and it does not help. Also with timeout circumvention the SATA flash card I was hoping to boot from (Transcend TS1GSDOM22V) is identified as follows: Bus 0: OK Bus 1: OK Device 0: Model: TRANSCEND Firm: 20080128 Ser#: 200804070005 Type: Hard Disk Capacity: 955.8 MB = 0.9 GB (1957536 x 512) IDE read: device 0 not ready IDE read: device 0 not ready Device 1: Model: Firm: Ser#: Type: Hard Disk Capacity: not available And then the card cannot be read. First attempt shows OK although the data written to memory are wrong, next attempts result in device 0 not ready. On the other hand, Linux (Debian ARM port) does not recognize the card either. So if this problem is not related to improper initialization, the question is how SATA flash differs from regular SATA drives with respect to SATA controller in 88F6281 and if it is actually possible to work with SATA flash on OpenRD. Can you #define DEBUG at the start of common/cmd_ide.c and rerun the test? Amicalement, -- Albert.

[U-Boot] U-boot with USB storage support for WonderMedia WM8505
Hi everyone, I'm new to this forum so im not sure if im in the right place. I tried searching for a solution but didnt find a solution. I have a 7 Netbook based on the WonderMedia WM8505 processor. Based on all the other forums ive read out there it looks like the hardware is very similar to a lot of the other 7 netbooks and 7 tablets out there. The netbook came preloaded with Windows CE 6. The problem ive got is I inherited the netbook broken. It appeares to be broken after a failed Android install. The serial console on the mainboard shows wload and u-boot starts fine. The problem looks to me like the Android installer has replaced the u-boot which was preloaded on the netbook. I looked through the environment variables in u-boot via the serial console and i saw an old bootcmd variable which referred to USB commands - usbinit, fatload usb 0:1, etc to boot the system however the uboot which is running on the netbook now has no such commands available. The new u-boot seems to support NAND, IDE, and MMC storage because commands for those storage devices are available, however the NAND and IDE commands both report no devices/controllers detected. Ive inspected the mainboard in this netbook and its onboard storage is a USB flash disk - that is its a 2gig NAND flash presented to the system via USB. So my question is this. Can anyone suggest where I could download a u-boot which has usb storage support which might run on this netbook? OR Can anyone give me any suggestions how I could make a compatible u-boot from source. Ive downloaded the source from the DENX website and had a look but the problem ive got is the 'make' program expects me to specify which system board to build the u-boot binary for but none of the board names in the u-boot source seem to resemble anything like the board in this netbook so I dont know which board configuration to use. These netbooks are so common and all have such similar hardware surely one of the board configurations would match well but which one?

Re: [U-Boot] U-boot with USB storage support for WonderMedia WM8505
Hi Albert, It would be great if i could get the original u-boot image and/or sources and maybe even the original Windows CE 6 from the manufacturer, however I dont know who the manufacturer is. I cant find anyone who makes Easy Notebook P701 or offers downloads for it. These netbooks appear to be mass produced as oem units and rebranded by numerous different sellers. for example, my netbook also matches the hardware description of the EPC 7 P701 netbook, and even a netbook called the Fashion 7 Netbook. The other issue is that this netbook has been tampered with as far as the warranty and support is concerned since the previous owner attempted to install Android which has replaced the wload, the u-boot, and the original Windows CE system cant be booted anymore so the store the netbook was bought from wont help. At this stage i really have no other choice but to take a chance and hope that someone with similar hardware can provide their working u-boot. Theres a lot of reports of users attempting to install Android on these netbooks and ending up in the same position im in but so far ive not seen a suitable solution. A lot of attempts to fix the problem involve installing a different u-boot, which ive attempted, but none of them appear to have usb storage support and therefore the flash disk is unavailable. My last resort is to go back to the online store where the netbook was originally purchased and ask someone on their forum if they will be kind enough to let me copy the u-boot from their working netbook.

So in you special case it may work, but if this is a blueprint for SPL on arm(v7) we should consider this. Nice catch. Actually, in my original OMAP4 series I tried to add support for disjoint bss to support my case. But now I realize that it works only for non-relocation case and that too only when the bss is at higher address compared to .text Basically disjoint bss is not relocation friendly. So here is what I propose: 1. Modify existing clear_bss sub-routine in start.S to take absolute addresses. 2. In regular u-boot, calculate the relocated bss address and pass to this function. 3. In SPL don't try to calculate the relocated address and directly pass the absolute address. If this is fine I will make the necessary changes in start.S in the next revision. So you would compute the BSS location in board_init_f() and pass that to relocate_code()? I was thinking of doing that in start.S itself. I haven't looked at all the details though. BTW, please note that I am not trying to support disjoint BSS in regular u-boot. I think it becomes complex with relocation + it doesn't seem to be worth when all SDRAM is at our disposal. So: 1. #ifdef CONFIG_PRELOADER part in start.s will just pass __bss_start and __bss_end to the clear_bss function(assumes no relocation). 2. #else part of above will assume that bss follows text and data(or at least that __bss_start _start), so add relocation offset to __bss_start and __bss_end, and pass them to the clear_bss() Does that sound ok? br, Aneesh ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
