Using the MF-PK 4.0 to create a working port on the AT91SAM9261 EK

[Manuel M.]

I try to use the opensource sample port of the AT91SAM9261 EK on the
evaluation kit.

Background Information to my Problem:
o) I compiled it with CodeSourcery (no errrors)
o) I managed to flash the bootloader (Tinybooter) with sam-ba (no errors)

The problem is, that the bootloader does nothing:
o) No debug-messsages on the serial
o) No startup of the wired-protokoll communication to deploy the
microframework TinyCLR itself.

I already checked the memory map (scatterfile), the debug_channel (COM 1),

Has anyone experience in compiling the sample Port to the AT91SAM9261 EK?
Does anyone have a similar Problem?

I just tested this scenario and it worked OK for me. A couple things to
verify:
1) Did you scrub NAND flash and erase all DataFlash first?
2) Where did you install Tinybooter.bin (NAND or DataFlash)? It needs to be
installed to DataFlash.
2) Did you send the Tinybooter.bin file or did you run the command "Send
Boot File" script? You should run the latter to ensure it is installed
properly.

Hi
Thank you for your quick response.

Yesterday i got the portbooter to work (with debug-port COM1).

Is there anything i have forgotten to configure for the tinybooter?

yes

yes i tried that; i think it runs but it currently uses the wrong
communication port.
(no debug messages and no communication with MFDeploy)

yes

I found the solution:

I had 2 simple Problems with the Port:
a) when the Tinybooter is compiled with gcc it includes the uart stubs
instead of the right ones
b) the flash version of the tinybooter is to big with debug included. So I
built a release version

Now it is deployable and ready to use.
