[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. I get the following output. ** U-Boot 2.0.0-rc5-git (Oct 31 2008 - 09:03:01) Board: Freescale i.MX27 ADS cfi_probe: cfi_flash base: 0xc000 size: 0x0200 NAND device: Manufacturer ID: 0x2c, Chip ID: 0xda (Micron NAND 256MiB 3,3V 8-bit) Scanning device for bad blocks Using environment in NAND Flash chip id: [1,882,1,01d] mpll: 398999390 Hz spll: 23725 Hz arm: 398999390 Hz perclk1: 2910 Hz perclk2: 26599959 Hz perclk3: 66499898 Hz perclk4: 26599959 Hz clkin26: 2600 Hz ahb: 132999796 Hz ipg: 66499898 Hz Malloc space: 0xa7b0 - 0xa7f0 (size 4 MB) Stack space : 0xa7af8000 - 0xa7b0 (size 32 kB) envfs: wrong magic on /dev/env0 no valid environment found on /dev/env0.

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. 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.

How can I reduce the frequency of operation through uboot? No. You mean the frequency cannot be reduced? Oh, I overread the 'how'. No, it cannot be reduced through U-Boot commands. You either have to adjust a lower frequency in the startup code or add a command that does the trick for you. 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. Sorry, I'm afraid I can't help you here without access to the hardware. But it will give some hints if you can verify that the NAND is working in general under U-Boot (or under Linux, which basically is the same driver) Regards, Sascha -- Pengutronix - Linux Solutions for Science and Industry Handelsregister: Amtsgericht Hildesheim, HRA 2686 Hannoversche Str. 2, 31134 Hildesheim, Germany Phone: +49-5121-206917-0 | Fax: +49-5121-206917-9 - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ U-Boot-Users mailing list U-Boot-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/u-boot-users
