[En-Nut-Discussion] Problems programming Ethernut3 (cfi primary command set 0 unsupported)

[José Vallet]

Hello all.

I am trying to program the flash of the Ethernut3 for the fist time. I
am trying to store the application in flash and run it from RAM. I am
trying to use "make burn", so I use jtagomat + OpenOCD + turtelizer2.

What I do:
1-Rebuild NutOS with the linker script at91_boot
2-Create the sample directory selecting Makeburn.arm-jom
3-Rebuild my application
4-Connect the turtelizer2 and run OpenOCD from nut/tools/linux
5-"make burn"

After this is completed the Ethernut does nothing. After resetting it I
can see that bootmon is still there.

My settings:
Kubuntu  8.04
NutOS version 4.6.4
OpenOCD straight from Ubuntu repos (0.0+r211-1)
jtagomat version 1.2.8
My Makeburn.arm-jom
--------------------
BURN=jtagomat_openocd
BURNMEMORY=FLASH
BURNFLAGS=-DDEVICE=0x1F0F0F0F -DIMAGE=./$(ITARG) BATCH at91-upl.jom
$(BURNMEMORY)

The outputs of the openocd and "make burn"

-----------------------------

The cfi error looks suspicious to me, but after some googling I am still
lost. Any hints are welcomed.


Thanks!
