U-boot & OLinuxino
« on: October 06, 2012, 05:39:21 PM »
I've made some progress porting u-boot to mx23.
As base I've used shamelessly stolen sources from repo of Otavio, branch wip and:
- added most of the registers of MX23 in place of those of MX28
- made mmc working
- trying to make usb host working ( unfortunalely this is not as easy for me to run  - HC is detected, but nothing more).

If somebody is interested in my work please send me a private message.
Maybe later I'd prepare some patches to easy include the sources in official u-boot repo, but now I'm interested in getting the uboot running in Olinuxino booting of USB / network.

Hope Otavio does not mind me working with sources from his repo,

T.

As far as I know, this project is active and involved are Otavio and Fabio Estevam. Please refer to this email http://tech.groups.yahoo.com/group/olinuxino/message/1926
I would suggest to contact them to coordinate future work.

I don't know if Fabio or Otavio read the forum here, anyway:

1) USB works, file read is stable
2) I haven't tried to load any kernel yet, so it is mostly untested
3) network over USB ( Olinuxino-maxi ) works, but not stable - uboot ping command sometimes hangs - have to try setting FS mode for HC, maybe polled IO for HS USB + MX233 is not a right combination.
4) My time for the next week is over,

regards,

T.

Hi T.szczyrba,

Good to know that you made some progress to mx23-olinuxino U-boot :-)

Do you have a git tree where we can look at your patches?

Does "mtest" work reliably, ie, without crash?

I can help you to submit your patches to the official U-boot project. Just let me know how I can test your patches.

Thanks,

Fabio Estevam

Or even better: please post your patches to the U-boot mainling list (u-boot@lists.denx.de), so that it can be reviewed there.

Thanks,

Fabio Estevam

I used to follow the mailing list but web forums ... I don't like ;-)

Please let's merge your changes onto mine the branch so we can send it for merging ... Please contact me by e-mail.
