Are you certain that the kit you have supports Lolo 2.4.0? See PCN 347 for more information.
http://www.logicpd.com/do...iMX31_SOM-LV_PCN.pdf

Production kits have not generally exhibited this behavior.
You can try the old standby of removing and reseating the SOM, this has been known to fix some connection issues.
Thanks

I want to go back to an earlier version but the function update update:

send update file:
update failed
error: update: file is not in update format (Found 0x837061c0)

And with fiel .elf:

load elf
loading from stdin:
0x80200000 7f 45 4c 46 61 28 38 80 34 8c d5 34 20 28 60 80 .ELFa(8.4..4 (`.
0x80200010 80 d5 c4 44 ea f0 9f e5 f0 9f e5 f0 9f e5 f0 9f ...D............
0x80200020 e5 a0 e1 f0 9f e5 f0 9f e5 b0 80 b0 80 b0 80 b0 ................
0x80200030 80 b0 80 b0 ....
ELF file must be: ARM, and elf-current:
load failed
...done
load failed
error: load: unable to read master header ()

Can I install other bootloader? What do I do to install it?

Thank you.

My litekit is Beta2 and For Beta 2 hardware: LoLo 2.3.1 or 2.3.3 must be used.

Be sure the binary checkbox is checked when you do the update.
I just completed this process on a Beta 2 Kit:

Thank you,

This was my problem.

But now, with logicloader 2.3.3 I don't mount cf.

I'm looking my new problem:

mount fatfs /cf
timeout resetting cf card
error: mount: failed to open (ATA)

I test the mount with delay , for example:
sleep 100; mount fafts /cf

But I have the same results:
timeout resetting cf card
error: mount: failed to open (ATA)

I send the results with LogicLoader 2.3.3

losh> ls /dev
S : nand0 0
S : flash0 0
S : null 0
S : serial_imx31_ff 0
S : config 0
losh> ls /
D : tftp 0
D : etc 0
D : dev 0

This is correct?

Thank you

Yes that looks correct.

PCN 348 has more information on CF on the Kits. Look under the LiteKit PCN.
fwiw - my J3 jumper is on 1&2 and the J4 jumper is off.

Richard

My compact flash is 256 MB and type I

I don't find the document PCN 348. Only I find PCN 347

Switch
JP2 is conected 5&6
JP1 is conected 2&3
JP3 is conected 1&2
Jp4 is off
J5, J8, J9, J17, all pins off

I can´t read the CF.
How do I read data from the SD card?
Are my jumpers ok?

oscarmarmar -

PCN 347 is under the SOM, PCN 348 is under the LiteKit - next section down.

The jumper settings look OK if you mean that one jumper is on 5 and one is on 6 for J2.
See the Quick Start Guide for JP2 settings- http://www.logicpd.com/do..._iMX_LITEKIT_QSG.pdf

If you have a different CF card I'd try that. We have had the best success with Industrial cards on the early kits.
Thanks

Richard
