JTAG interface board
Am looking at buying a Freerunner for use on a embedded course. When I looked at buying last year the phone came with a developer board...and a pretty case! If I buy a freerunner now it will not come with the interface board. What restrictions will this put on my development. Will I be unable to modify the U-Boot code. Can I flash all the blocks within the flash? TA Leo "In a study, scientists report that drinking beer can be good for your liver. I'm sorry, did I say 'scientists'? I meant Irish people."

But if you mess up programming uboot, your going to brick you phone. They sell a JTAB / serial port board for the freerunner. This board is nice because it can work on any arm system that has the 20 pin JTAG connector. Openmoko still sells the "Dboard" on the US direct site http://us.direct.openmoko.com/. Basicly its a FTDI high speed usb to serial interface chip wired up to be a JTAG. Its nice because its a simple open jtag system, that programs like xilinx and openOCD can operate. -- Peter Fetterer KB3GTN The force is like duct tape.

So without the board you can still play around with bootloader, kernel and rootfs, and if you stuff up, then the u-boot in NOR will still be available to use to reflash and recover.

Yes you don't have to fear trashing U-Boot in NAND at all, and you can't trash NOR U-Boot without a debug board. The main downside is that if you were planning to work on bootloader or kernel, you will miss out on being able to see the serial console traffic. - -Andy -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkj3TJsACgkQOjLpvpq7dMqQoACeI3pE6SJgfiHwT6fvL7YpoSJr gHEAniL1/BNZRgjeoNYk/khw0YuJimPs =qIMe -END PGP SIGNATURE- ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: JTAG interface board
the debug board is now sold separately for 100USD If you like the case you can try this. http://www.thepelicancases.com/smallcases.html Leo McManus wrote: > Am looking at buying a Freerunner for use on a embedded course. > > When I looked at buying last year the phone came with a developer > board...and a pretty case! > > If I buy a freerunner now it will not come with the interface board. > > What restrictions will this put on my development.
