u-boot bootloader

I'm about to port the latest u-boot-1.1.2 bootloader to the STR720 evaluation platform...

alraedy done for some PPC/m68k platform and TriCore is in the pipeline (including opensourced jtag flasher for Linux/Cygwin).

Is there absolutely no documentation available how to initially program the flash memory on the evaluation board or load the a small flash programmer into internal RAM?

Or is the STR720 only meant to be used by expensive 3rd party tools?

Maybe someone sponsors a STR720 evaluation kit for putting STR720 support into official u-boot cvs tree?

I have implemented a programmer for the 71x range, ram is loaded via the jtag channel with the programming software. The dcc comms channel is then used for the main transfer of code to program flash.

The code is based on R.Longo jtag code which is available on the net.

I am currently adding support for external flash so will keep you posted.

It is included in the free Anglia (www.angliac.com) STR7 toolchain/ide which has been developed.

Happy New Year !

Which tool you mean?

''IDEaliST'' which looks like Eclipse?

Don't see any ''free'' stuff on this site.

Any sources for the JTAG programming stuff or do you know where to get the specification?

IDEaliST is a free ide written in house, also available is a arm7 gcc port configured for the str7 range of devices.

A link to download the software should be added very soon if you don't want to fill the form in.

Think wiser to switch to AT91RM9200 from Atmel..doesn't has PCMCIA but built-in ethernet and USB host and runs up to 200MHz and is available since 2003 (o;

And yeah...Atmel made the ''u-boot'' port as well (o;
