Thanks for your answers !
To Jorge_Gonzalez :
I only plug the usb cable directly on the card, si if I understood well, I use the embedded OSBDM/OSJTAG :smileyhappy:
I'm using Codewarrior 10.5.
When I search the flash configuration file, I don't find the good one ! I have downloaded a blink_led project on the freescale website (which worked well with the debug), and by default it is K40DX256Z.xml, is it OK for a K40X256VMD100 ?
This blink_led project which worked very well in debug mode allowed me to choose between ram and flash for the debugger (as shown in "Capture2.PNG"), both of them worked well without any difference but now they have differents bug :
- the flash mode stucks the downloading at 99%
- the ram mode shows an error which says : No source available for "0x656A6F72 (0x656A6F72)() " (as shown on "Capture.PNG")
To ZhangJennie :
Your method didn't change anything :smileyconfused: I also tried to make a new workspace, I tried on my friends' computer (where it worked well too) and the same problems everywhere ...
Thank you
