Re: jtag & uboot

Hi Jens. I'm just spinning-up a 2.6.24 kernel on a powerpc MPC5200 board. After some wrestling I got to EXACTLY the place you did: successful boot but with a VERY long delay between apparant kernel load by u-boot and console output.

Have you had any luck solving this delay problem? Can you offer me some advice?

Thanks!

Re: jtag & uboot

Hello smile
I am a old time coreboot developer and I have done a fair share of device hacking in my day. I just picked up a DSM-G600 for a fun side project. I was pretty disappointed in how limited the original u-boot is on this little box. So...
I plan on building a current dsmg600 target board for u-boot and hopefully i can get it approved to submit it to the u-boot repository. I don't know if any of you know but all the original d-link files for u-boot and Linux can be found on the d-link GPL website:

http://tsd.dlink.com.tw/

I have taken the d-link u-boot source and diff'd it to the original u-boot 0.2.0, so know I know what changes need to be made to get a full current version of u-boot running on this little box. Haha the d-link developers sure did alot of improper code hacking..... Any ways I am attaching the diff in case your interested in checking it out. So at this point I am going through all the diff code and compairing it to the most current version of you boot to see what needs to be changed.

Also I found this webpage on howto jtag a aMPC824x (sandpoint) board using a ByteBlaster cable and UrJTAG.

http://sun.hasenbraten.de/~frank/docs/mpc824x_JTAG.html

I have ordered my ByteBlaster jtag cable, just waiting for it to come, hopefully I wont need it but just in case i brick the board, lol.

Also because the chipset supports dual IDE channel I ordered a CF IDE Adapter and CF card, I should be able to setup a master/slave config. I hope the CF and IDE hard drive will bot be able to fit in the case?  I will be using it to develop a Modern embedded Linux OS for this little box. Because the 2.6 kernel will probably be too large to fit in flash it and the ram-disk will either boot from CF or USB possibly?

Anyways Thank you very much for your hard work on getting the jtag up and running jens! Much appreciated smile

Re: jtag & uboot

Interesting... Looks like u-boot doesn't have any support for the IP1000A. That probibly why the original developers never added it in. Lets take a look at how altboot does it...

Re: jtag & uboot

I think the NetBSD altboot stg.c driver will work just fine smile
