[U-Boot-Users] smdk2413 support?
by Allen Curtis 20 Oct '06

20 Oct '06

Does anyone have a smdk2413 patch for U-Boot? We have a very old, mutant version from Samsung which supports the 2413 processor with NAND boot capability. I am working on porting this functionality to the latest state of development but time is running short. Most of the processor support has been implemented but NAND and NAND boot support are still a problem. If you have a 2412 version, that would also help. TIA - Allen

[U-Boot-Users] NAND access via custom interface
by Jack Hab 19 Oct '06

19 Oct '06

Dear All, I'm porting U-Boot to our hardware based on Virtex-II FGPA. We have NAND device which cannot be accessed directly but only via our interface which takes care of all the control lines and sends the address/command/data bytes automatically. I understand, low-level macros like NAND_CLRCLE can be skipped. Will it be OK if I implemet only NAND_WAIT_READY, WRITE_NAND_xxx and READ_NAND macros? Or anything else is required. Do I need to set any structures manually? I couldn't find who populates struct nand_chip with info, at which stages it occurs. Thanks.

[U-Boot-Users] Load OS over PCIe
by Ralf Trübenbach 19 Oct '06

19 Oct '06

Hello, I'm thinking about how to boot an operating system over PCIe. My device is a PCIe endpoint and can for example be connected to a normal PC (PCIe interface). U-Boot shall be loaded from PC to the µCs (MPC8540) internal SRAM. When uboot is once started I have to load the OS- binaries from PC. For that purpose I'm thinking about a shared memory interface. My Question: Is there already a shared memory interface I can use integrated in U-Boot?

[U-Boot-Users] PXA270 USB device support
by Rodolfo Giometti 19 Oct '06

19 Oct '06

Hello, I've just got a functional USB device support for Linux and now I'd like adding this support to u-boot too. I wish to know if someone else is working on this topic in order to join the efforts. Also I'd like to have some suggestions on how to do the job. I suppose I should take a look at file cpu/ppc4xx/usbdev.{c,h}, is that right?

Please try to be as specific as possible when describing your problem. No top posting and no full quotes helps as well. Answering the questions I sent you will be a good step in finding a solution, too. I repeat my questions which have not been answered: Which board and processor are you using? Many eval boards from Renesas are named "Solution Engine". I have one named "Solution Engine MS7720RP01" and it is for the SH7720 processor. If it is not the official U-Boot distribute by http://www.denx.de/, where did you get it from? Do you have the source code of U-Boot and which target did you use to compile it? Is it an unmodified kernel from http://www.kernel.org/? If not, where did you get the kernel from? Using which configuration options did you compile this kernel? Best Regards, Mark PS: Outlook QuoteFix helps a lot if you have to use Outlook but still want to properly reply to a post on a mailing list. http://home.in.tum.de/~jain/software/outlook-quotefix/
