Luminary LM3S5B91

 Luminary LM3S5B91

I have problems to flash my program.
Small programs (~400Byte) works, but my current program (~12k) I cannot flash correctly.

I'm using Keil v4.11 and Ulink2. Erase complete and erase partly works. On programming I get the error 'Flash Timeout'. I'm using a quartz of 8MHz. JTAG Clock max is 500k. The Flash algorithm ist LM3SXX.

Ideas?

It's a problem like:

and

http://www.keil.com/forum/docs/thread16541.asp

But note, that erase is working and it seems, the maximum working size is 1k. I have a customer hardware and I think, I cannot use a other Flash tool. It use the uart, doesn't it?
But also I did not find the LMI Flash tool to check it.

ULINK-ME has the same problem.

After changing the Flash Algorithm described in the second Thread, I have the same problem described in the first link (Cannot load Flash Programming Algorithm).

With an Eval-Version you are not able to create a *.FLM-File! This is the reason why you get the error-message

Better would be a compile error...

Keil v4.12 solved the Flashing error.
Thanks to the TI and Keil support.
