u-boot - UART does not show any output under burn mode #2

Open nrmmota opened 10 years ago

nrmmota commented 10 years ago

Hi,

I've followed your tutorial on how to flash the u-boot. But so far the UART does not show anything regarding the new u-boot. UART works fine when its in boot mode. While in burn mode it doesn't work.

Am I doing something wrong?

My imx_usb command seems to be working just fine. I have the same output.

Regards, NRM

I've just moved across the ocean and my tbs2910 is lagging behind me in some container on some boat by 8 weeks. So I can't really test this at the moment. Try to remind me in ~2 months and I'll try to remember to test it when I can.

It sounds like maybe your u-boot build is broken. Have you tried with a known good u-boot binary?

Hey,

I tried both with an imx uboot and your compiled uboot.imx (2014.rc1), none seemed to work. I'll find some other way I guess.

Good luck btw, moving across an ocean sounds big :D

@nrmmota: I hope you haven't given up on this! I've unboxed and dusted off my TBS2910 and I'm checking out the state of things here on my end.

After poking around a bit, it looks like there's a lot of good news to be had! Both u-boot and the Linux kernel seem to have officially added support for our TBS2910s, so things should be a whole lot easier now.

I'm in the process of updating the wiki and the repo here to reflect these changes and I'm doing some new builds. I hope I'll be able to post a new release containing the very latest u-boot.imx and kernel binaries in the next few hours here.

Hopefully that solves your problems. Stay tuned!

Hi,

Glad to know your back. Picked up uboot and kernel from mainline and it worked. Stilk don't know how to flash z/uImage into disk but I'm still learning.

Waiting to see your updated Wiki's.

What are you trying to boot from? u-boot needs to know where to look for your kernel image.
