U-boot 3.4.23 - mmcinit has odd output

[samweber]

Last week I was yammering about v3.4.19 corrupting its environment.  To recap, the "console" environment variable was being set to "a0000".  That bug was declared fixed in v3.4.23.  Oddly, when I upgraded to v3.4.23, reset the target, and re-entered the necessary environment variables in the hopes of one day actually getting the SD card to support the RFS, I now see the "a0000" string as part of the output of the mmcinit command.  A capture of my Procomm session is shown below.  I do not, however, see the "cmd 8, error 0201" the first time I enter the mmcinit command.  With v3.4.19 I always saw the error the first time I typed mmcinit but never on subsequent attempts.

Override Env parameters? (y/n) n

Since there was a bug in 3.4.19 regarding environment console, you should ask uboot to override the Env parameters when upgrading to new uboot (3.4.23) during the bubt procedure.

You can also do it by entering resetenv after uboot upgrade and perform reset afterwards.
Before resetting your uboot Env, save them as text somewhere...

[samweber]

resetenv does not appear to clear the issue:

Hi samweber,

OK, so now it looks like this bug is fixed, please try it out.

-rooster

[samweber]

The plot thickens a bit.  This round of bubt seems to have angered the flash.  Unless I typed something stupid, I now seem to have a different problem.  The mmcinit command did clear up as advertized.

what is the value of nandEcc?

[samweber]

Marvell>> printenv nandEcc
nandEcc=1bit

[rooster]

can you try re-flash the uImage to 0x100000 (from uboot) while the DOK (with uimage on it) is connected to the plug:
>usb start
>fatload usb 0 0x00800000 uImage
>nand erase clean 0x00100000 0x00400000
>nand write.e 0x00800000 0x00100000 0x00400000

[samweber]

Here's a summary of what happened.

0. I entered the command sequence specified (note: The uImage file on my USB storage media is from the installer that everyone but me can make work.  I did this in hopes of making progress towards the end goal of having RFS support on my SD card.)
1. The commands seemed to work without incident.
2. I did a printenv and noticed a number of potentially bad omens:
   a. "console" is whacked to a0000 again.
   b. "nandEcc" now appears to have a value of "bit" and seems to have an embedded carriage return and/or line feed.
3. Boot process emits a read failure.  No visible output after the kernel is decompressed.

Disclaimer: Always the possibility of a boneheaded keyboard error on my end.  I find that occasional typing mistakes on critical commands help reinforce one's humility.

Your bootargs looks wrong,

ipaddr=192.168.76.42
bootargs_root=root=/dev/mmcblk0p1 rw
bootargs=console=ttyS0,115200 $(bootargs_root)
bootcmd=mmcinit; nand read.e 0x00800000 0x00100000 0x00400000; bootm 0x00800000
stdin=serial
stdout=serial

I think it should be bootargs=console=ttyS0,115200 root=/dev/mmcblk0p1 rw

good luck

I'm pretty sure $(bootargs_root) gets expanded to yield the suggested line.  The reason I'm confident is that rooster would have jumped on me immediately if the answer were simple.  His silence makes me think I have identified a nastiness that transcends my unreliable typing skills.

Hi samweber,

The reason I asked about nandEcc is that I noticed that this env gets a null value and a new env appears: bit.
So to finish my installation I had to set he nandEcc=1bit.
In your case I see the same phenomenon but the uboot did load the uImage from nand and manage to run it.
So basically it looks OK, the next step would be setting the right uboot env to make kernel boot from rootfs on SD.

Please look in the installer (aplug-installer-v1.0\uboot\uboot-env\uboot-mmc-custom.txt ) for reference regarding uboot settings.

I will try to understand the nandEcc issue.

Hi,

The nandEcc bug found in last uboot version I uploaded: http://plugcomputer.org/plugforum/index.php?topic=921.msg5698#msg5698

this fixed with this image, please use it with your installer with the attached
