OMAP5432 at home !


How are defined the default parameters (well the card boots) if no bootfile is present ?

In the .dtb ?
 
BTW I bought a micro USB 3 to female adapter, pluging devices inside does nothing :/.

Your kernel boots fine aTc, thanks !
 
default parameters are compiled into u-boot itself.

usb 3.0 otg not working is normal, TI don't really seem to support it, or have bothered to implement it properly.

http://e2e.ti.com/support/omap/f/885/t/275115 and http://e2e.ti.com/support/omap/f/885/t/277258

http://processors.wiki.ti.com/index.php/Linux_Core_DWC3_User%27s_Guide#Features_NOT_supported

I don't expect the situation to be any better with the igep board, since their stuff is heavily based on TI's.

Support from igep isn't that great either, they won't update the .dts for the board to support more recent kernels. So you're pretty much stuck with their "ancient" 3.8 kernel.

hns did try a few things with his kernel version, but that didn't work in usb 3.0 mode either

That's sad.

Trying your rootfs, things went strange, I have tons of :

weird, does the first run wizard show up on the hdmi output ?

And did you make sure to copy all the kernel modules and firmware to /lib ?
 
I'll connect hdmi.

I copied only the base modules directory, not the wifi addons.

---EDIT: ah, maybe I missed firmware :) .

I don't use wifi.

I took /lib/firmware/ti-connectivity/* from Slack, and it finished booting.

What are login/password ?
 
Last edited by a moderator:
I have tons of wlcore crashes.

Systemd hadn't finished booting in fact...
 
login/password is root/root

The normal users are set up in the first-run-wizard

I don't remember wally having these issues with his board.

The most weirdness he had was caused by him not extracting the rootfs to the sd card as root.

Are you sure you're using, and booting, the right kernel and modules ?

you could retry reinstalling the complete rootfs, with all the modules and firmware, maybe something went wrong during the setup stage on the very first boot.
 
^ Jessie has password auth for root disabled in sshd by default, this was not the default in Wheezy

I don't get how I mount the NAND :


$ ls /dev/mmcblk1
mmcblk1       mmcblk1boot0  mmcblk1boot1
---EDIT :

Some fdisk output :

the lite version has no NAND which I can tell you have due to the 1GB of RAM.

If you did infact order the 4GB model. Good luck getting iGEP to fix the issue.
 
ignore the boot0 and boot1 partitions, the rest just behaves like a normal sd card, just one you can't remove.
 
According to you (Wally), Kernel 4.0 needs a DTS file and iGEP don't have that file and can't be bothered making one.

But isn't a DTS a text file with parameters that is compiled along with the kernel ?

Great !

I suppose i can do the fat + ext4 partition writing MLO and u-boot.bin in fat first ?

---EDIT : didn't work :/

it should work, but just like booting from a normal sd card, the partitioning and formatting and copying of files has to be EXACTLY right, or it won't do anything.

You might have to change the switches on the board to make it boot from emmc though. igep should have some docs on them somewhere.
