Re: [U-Boot-Users] UBOOT port to i.MX27ADS - NAND issues
Hi Sascha, Can you access the NAND device? Before trying to boot from the device should make sure that it works using normal U-Boot commands. The only command related to the nand flash when I type help is nand. Could you please tell me some commands to read and write the nand that would work from the uboot prompt? Where could I find more info on this? Well the trick is that There are no other commands for nand. When the NAND device is initialized you should have a /dev/nand0. From there on you can partition the device using addpart, for example like this: addpart /dev/nand0 256k(uboot),256k(ubootenv),2M(kernel),-(root) This gives you the partition devices /dev/nand0.uboot and so on. You then add bad block aware devices ontop of these partitions: nand -a /dev/nand0.* You can use the standard commands like erase / cp / md on these devices. I did the same. When I do a devinfo, I get: uboot:/ devinfo devices: |cs0 |mem |nor0 ||self0 |`env0 |ram0 |eth0 |phy0 |nand0 ||nand0.uboot ||`nand0..uboot.bb ||nand0.ubootenv ||`nand0.ubootenv.bb ||nand0.kernel ||`nand0.kernel.bb |`nand0.root ||`nand0.root.bb |defaultenv |filesystem: / |filesystem: /dev drivers: imx_serial partition fec_imx27 miiphy nand_device imx_nand cfi_flash imx_spi mc13783 mem ram rom nand_bb ramfs devfs Now, when I use the cp command, I get uboot:/ cp env/config dev/nand0.uboot.bb write: I/O error uboot:/ Is the the right way of doing it, or is there any other step I am missing out. I tried the same with the Samsung device but it gives the same error. Thanks in advance. Tiju Be the first one to try the new Messenger 9 Beta!

[U-Boot-Users] UBOOT port to i.MX27ADS - NAND issues
Hi Sascha, The Nand port to imx27ads is booting when I use a Samsung device (128MiB, 3.3V, 8-bit, 512page). Now my requirement is to boot from a Micron device (256MiB, 3.3V, 8-bit, 2k page). Part num: MT29F2G08AAD I modified the line in imx27ads.c to imx_nand_load_image((void *)TEXT_BASE, 256 * 1024, 2048, (2048 * 64)); //256MB, 2K Q Is this correct? I have also commented some lines in nand_get_flash_type which checks the Manf./device ID again! Once modified, I loaded the image to the RAM location 0xa7f0 and executed.

Re: [U-Boot-Users] UBOOT port to i.MX27ADS - NAND issues
Hi Sascha, The Nand port to imx27ads is booting when I use a Samsung device (128MiB, 3.3V, 8-bit, 512page). Great! Care to send patches? That would help answering further questions as well.. Sorry, I know its a basic question but how do I make a patch file? Else I can send you the file I modified. Now my requirement is to boot from a Micron device (256MiB, 3.3V, 8-bit, 2k page). Part num: MT29F2G08AAD I modified the line in imx27ads.c to imx_nand_load_image((void *)TEXT_BASE, 256 * 1024, 2048, (2048 * 64)); //256MB, 2K I don't know your NAND chip, so I can't say anything about the block size, but otherwiese it looks correct. Thanks. I have verified that the block size is correct. Can you access the NAND device? Before trying to boot from the device should make sure that it works using normal U-Boot commands. The only command related to the nand flash when I type help is nand. Could you please tell me some commands to read and write the nand that would work from the uboot prompt? Where could I find more info on this? But once I program the uboot image to the micron flash, nothing seems to appear on the UART. I am using the Ronetix PEEDI JTAG programmer. 1. Is there anything/anywhere else I should modify the uboot code for the micron nand flash to boot? I think not, but then again, it would work, right? I went through the code and could find only this to be modified. I am worried weather there are any timing related differences between the samsung and the micron. 2. How can I reduce the frequency of operation through uboot? No. You mean the frequency cannot be reduced? 3. If I do single stepping, it seems that the first 2k data is being copied successfully from the SRAM to the DDR. But if I execute/give a go nothing appears on the UART, but PC=0x0004. Place a breakpoint after the first 2k are copied and single step further. It looks if I single step all the 2K bytes are copied to DDR. But if I just execute, in the 2K everything copies except the first 512bytes. Regards, Tiju Connect with friends all over the world. Get Yahoo!

Re: [U-Boot-Users] UBOOT port to i.MX27ADS - Network and NAND issues
Hi Sascha,
2. Is it possible to do a NAND boot on i.mx27ads board with uboot? If so

phycore i.MX27 module. So the NAND driver inself is in place, only the
board specific bits are missing.. You can use board/pcm038 as a template.
Thanks. The network is up now. But when I try to compile using pcm038_defconfig
(just to test the nand support) some errors are generated by the assembler. I
am using the compiler from ptxdist.
The command used is:
make ARCH=arm CROSS_COMPILE=/opt/OSELAS.Toolchain-1.1.1/arm-v4t-linux-gnueabi/
gcc-4.1.2-glibc-2..5-kernel-2.6.18/bin/arm-v4t-linux-gnueabi- pcm038_defconfig
and then when compiled the following errors occur.
CC drivers/nand/nand_base.o
{standard input}: Assembler messages:
{standard input}:4130: Error: selected processor does not support `clz r2,r2'
{standard input}:4142: Error: selected processor does not support `clz r3,r3'
{standard input}:4143: Error: selected processor does not support `clz r1,r1'
make[2]: *** [drivers/nand/nand_base.o] Error 1
make[1]: *** [drivers/nand] Error 2
make: *** [drivers] Error 2
Is a different compiler version used in compiling with the nand support or
anyother changes could solve the problem?
Thanks and Regards,
Tiju

[U-Boot-Users] Porting NAND drivers
Hi All, I am interested in writing a NAND flash driver for my freescale i.MX27ADS board in Redboot. 1. Could anyone suggest me wether it is possible to take the u-boot's NAND flash generic driver and modify it and port it for Samsung NAND flash in redboot? 2. Or is there an easier way I could start porting the NAND driver to i.MX27 ADS board in redboot? Any suggestion is greatly appreciated. Thanks in advance.

[U-Boot-Users] Linux kernel startup
Hi Harald, The serial issues were solved. As u said, the problem was with the RTS/CTS. I disabled all the hardware control signals and some modifications with the relocation section in the start.S and it started working. Now the issue is with the kernel CRC32 check. I compiled a kernel with the smdk2440 architecture and I do the following. $ arm-linux-objcopy -O binary -R .note -R .comment -S vmlinux linux.bin $ gzip -9 linux.bin $../u-boot-1.3.2/tools/mkimage -A arm -O linux -T kernel -C gzip -a0x30008000 -e 0x30008000 -n Linux kernel -d linux.bin.gz uImage.bin The size of vmlinux is around 25MB. When converted to linux.bin it is 3GB, when gziped it is around 4MB and when done an mkimage it remains almost the same.. The output is as follows: U-Boot 1.3.2 (Apr 7 2008 - 12:14:29) DRAM: 128 MB Flash: 32 MB Using default environment In:serial Out: serial Err: serial Hit any key to stop autoboot: 0 ## Booting image at 3300 ...

Bad Data CRC What ever kernel image I load it tells the same ie. Verifying Checksum ... Bad Data CRC. I even tried the uImage.bin which was available on openmoko site and the same error occurs. Is the error with the bootloader or the kernel image? If so what are the changes to be done? Thanks in advance. Tiju Messenger blocked? Want to chat?

Re: [U-Boot-Users] Linux kernel startup
Hi Jerry, This is indicating you have major link / memory map / coding issue(s). vmlinux should be around 1MB, not 25MB! linux.bin should be around the same size as vmlinux. Having linux.bin grow to be 3GB indicates it has major holes in it that objdump is filling with fill values. Loading a 3GB image (compressed to 4MB or not) is simply not going to work. I will look into the kernel sections and try to figure it out. It maybe the problem with my compiler. But my other major problem is that, what ever be the size of the kernel, it gives me a Bad Data CRC. I tried with prebuild images from the openmoko (which are working images on openmoko 1.5MB) and still it shows me the same error. We have almost the same architecture as theirs. Does this have to do anything with the u-boot or some other issue? Thank You, Tiju. Meet people who discuss and share your passions.

Re: [U-Boot-Users] Linux kernel startup
Hi Harald, Please see my other e-mail response about this. I still believe there might be some wrong memory / bus / core clock timing and or voltage issues. We changed the memory clock to a lower frequency(90MHz to 67MHz) and the the Bad Data CRC error has gone. Thanks alot. Our settings are: EXTCLK = 12MHz FCLK = 271 MHz HCLK = 67.75 MHz please try to use u-boot's built-in memory verification code to veryify your memory before trying to boot a kernel on it. We will do this now. We are writing the kernel image directly to the ram to 3300. Therefore as for now it is not copied from the flash. Is the hardware a prototype of a new board, or is it proven, verified hardware? Yes, the hardware is a new prototype. The output now is as follows: U-Boot 1..3.2 (Apr 7 2008 - 17:25:31) DRAM: 128 MB Flash: 32 MB Using default environment In:serial Out: serial Err: serial Hit any key to stop autoboot: 0 ## Booting image at 3300 ...

Re: [U-Boot-Users] s3c2440 -- serial_init
Hi Michael, I have verified all the RAM initializations in board/smdk2440/lowlevel_init.S and it seems to be fine. The other changes that I have done are 1. In the board/smdk2440/config.mk file I changed TEXT_BASE = 0x33F8 to TEXT_BASE = 0x because I am booting from the NOR flash. The NOR flash address range is 0x - 0x0800. The RAM address range is 0x3000 - 0x3800. If I compile it with TEXT_BASE = 0x33F8 it does not run at all! 2. When I changed this I found that it has a clash with the stack building in cpu/arm920t/start.S. Therefore I changed it to . /* Set up the stack */ stack_setup: /* ldr r0, _TEXT_BASE */ /* upper 128 KiB: relocated uboot */ mov r0, #0x33 /* make stack at 33F8*/ mov r0, r0, lsl #24 mov r1, #0xF8 mov r1, r1, lsl #16 orr r0, r0, r1 ... Would these be a problem for the memory initializations? Thanks in advance Tiju Hi all I am trying to port u-boot to a s3c2440 samsung processor. I applied the smdk2440 boards patch (almost similar architecture) and trying to modify it for our board's requirement. But during the serial_init it goes to the _serial_putc and then after certain loops it goes to the hang function and hangs there. What could be the problem? Or am I doing some wrong initializations?

The RAM address range is 0x3000 - 0x3800. If I compile it with TEXT_BASE = 0x33F8 it does not run at all! 2. When I changed this I found that it has a clash with the stack building in cpu/arm920t/start.S. Therefore I changed it to . /* Set up the stack */ stack_setup: /* ldr r0, _TEXT_BASE */ /* upper 128 KiB: relocated uboot */ mov r0, #0x33 /* make stack at 33F8*/ mov r0, r0, lsl #24 mov r1, #0xF8 mov r1, r1, lsl #16 orr r0, r0, r1 ... Would these be a problem for the memory initializations? Thanks in advance Tiju Hi all I am trying to port u-boot to a s3c2440 samsung processor. I applied the smdk2440 boards patch (almost similar architecture) and trying to modify it for our board's requirement. But during the serial_init it goes to the _serial_putc and then after certain loops it goes to the hang function and hangs there. What could be the problem? Or am I doing some wrong initializations? Are you sure that the memory inizializzation is correct? Regards Michael Unlimited freedom, unlimited storage.

[U-Boot-Users] How to patch u-boot?
Hi Could someone help me out with patching the u-boot. I downloaded the source code of u-boot-1.1.6 and untared it. Then I do a $cd u-boot-1.1.6 $svn co http://svn.openmoko.org/trunk/src/target/u-boot/patches/ $patch patches/boot-menu.patch patching file bootmenu.c can't find file to patch at input line 154 Perhaps you should have used the -p or --strip option? The text leading up to this was: -- |Index: u-boot/board/neo1973/gta01/gta01.c |=== |--- u-boot.orig/board/neo1973/gta01/gta01.c |+++ u-boot/board/neo1973/gta01/gta01.c -- File to patch: This is what comes Is this the way to do it?
