new NAND u-boot-multi version

The new u-boot-multi NAND version has support for booting Linux from NAND, and it will also have the memory timing fixes needed to boot problematic devices such as Mele 1.7 and others.

Edit: The timing change was reverted, as, contrary to info from guillame, it is only needed for MMC SPL. That is what hno said anyway. I have no way to test. So YMMV. . .

Worked fine for me booting both Android and Linux from NAND, and Linux from MMC, etc.

You are one that requested this. So maybe you can test on one of your 32? It can't hurt to take one out of service for a few mins. to help improve the platform. I really need feedback. I don't like being the only tester. . .

hi,

I'm not living in my datacenter but i have spares ;-) i will try to do a test tomorrow and as you, i have not a lot of time.
The last v1.7 i got have a kind of antenna soldered on the board. I will try to make pictures of it. I don't know exactly what is it for... wifi ? nfc ? don't know. You'll see.

THANKS! Currently I'm adding the NAND Linux support to the MMC version. It works for me, but it would be nice to have other testers to hopefully locate any possible bugs. I used your DDR timing patch on the NAND version. But hno has further timing updates for uboot-allwinner that I plan to add to the final versions.

wifi ? nfc

Mele does not have NFC. So I would expect it is for wifi.

Some guys around reports me the patched version from the test package i've made to check between spl and u-boot is working and not anymore the hno current tree + patch PLL.

Strange. I will test it.

This thread is for the NAND version. No SPL. I changed thread title to reflect that.

I thought you were using NAND version for all those Mele's? Please don't tell me you have an MMC in each one!

classic u-boot on MMC for the automatic install.

Reformating the nand, put my kernel and reuse the stock uboot from nanda to boot on nandb (3.9Go). Simple and easy. I think there was no m-uboot when i have start.

Ah. Okay. I figured you compiled lichee from hno or hipboi with your own env. But I suppose you could just use serial to edit the existing env.

No. There was not.

The NAND multi version should be very helpful to many who don't have serial, who want to also keep Android, or who have MMC in the slot but do not always to boot from it.

Hello,
everything ok using multi u-boot 'Linux on NAND'.

Just one question. Linaro (i use as rootfs, but Ubuntu/Lubuntu the same) show 320M of memory.
Using the mem=512M parameter in u-boot should be solved, but how we can put this parameter in uboot.conf (useful text version instead image file)??

Thank you
Claudio

Hello,

you need to use boot.scr file. This works for me (tested on MK802+ with NAND U-Boot):

1. Create file linux/conf.d/boot.cmd on nanda partition
2. Content of boot.cmd:

setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 mem=512M loglevel=8 rootwait
fatload nand 0 0x43000000 script.bin
fatload nand 0 0x44000000 linux/uImage
fatload nand 0 0x45000000 linux/uInitrd
bootm 0x44000000 0x45000000

Note: Modify bootargs as per your needs (e.g. set your root device, include modules in rd.driver.post="" if you use them, etc.)

3. Compile boot.cmd (you need to install uboot-mkimage package):

mkimage -C none -A arm -T script -d boot.cmd boot.scr

Now U-boot should pick up boot.scr file and use boot instructions from it.
After boot Linux shows following kernel parameterers:

cat /proc/cmdline
console=ttyS0,115200 root=/dev/mmcblk0p2 mem=512M loglevel=8 rootwait

cat /var/log/syslog | grep Memory:
Jan 1 01:00:38 prgvn1002 kernel: [ 0.000000] Memory: 512MB = 512MB total
Jan 1 01:00:38 prgvn1002 kernel: [ 0.000000] Memory: 380720k/380720k available, 143568k reserved, 0K highmem

Solved without compiling any other boot files.
The workaround is append the "mem=512M" to already defined variables, as "mac".
That is (example):

mac=<mac_address> mem=512M

Regards,
Claudio


To save memory (MALI reserved), i hope someone could compile 3.0.39+ or 3.0.42+ without MALI=Y flag. This will be for server purpose.

Hi,

which image did you use for your MK802+ ? I tried many image, uboot, script.bin and so on and it does not work at all. Mine is labelled MK802+ , inside it uses an A10S (not a A10) processor.

many thanks.

I've had the SAME problem. My guess is the u-boot is different for the A10s because it shows as a sun5i instead of a sun4i. I've even tried looking for a version that would boot on the AllWinner A13. I believe that too is a sun5i.

Yep A10s is closer that A13 rather than A10. So Sun5i is a good choice, but before I think U-Boot is different as you said and Pio mapping have to be found on that processor I think this is the key to have a first success with it. Unfortunatly informations are very poor after spending hours to search :/

Hello,

How did u implement fatload for nand? How can i implement the same in my U-Boot 2012.07 code? Which version of U-Boot are you using which has support for fatload nand?
Is it possible to share the reference code or reference document.

I want to implement this functionality for my IPQ8064 SOC to boot kernel from an mtd partition of FAT filesystem.

Thanks.

Hi Jees,
