it could be that on jlink-project setting-target interface I did not set speed on automatic but left 200khz 12000khz ???
I would not burn another mcu ......
the project file it should be open to: am91sam7s256.jflash(9kb) or am91sam7x256.jflash(18kb)???

Hi Mates
I want to replace at91sam256 on my carprog, because it is broken, I soldered an NEW at91sam256 ( B ) but cant flashing by Jlink,
j link does not detect carprog , also laptop does not detect it with new at91sam256,
it is because of new at91sam256 is blank ??? or by another reason ?
thanks

obviously you didn't power up your PCB

Hi Mikroel
I did carprog power up with USB ( via laptop ) and with externe powersupply ( 12 volt power jack )..

Yes, but your J-Link didn’t reckonize that, so you have some problem with power supply

No no the tool was fine, then I updated firmware with J-link and carprog no longer worked. I just remember to have put OBD + carprog banana and have done obd and tool tests and it did not work +. That this.

before error " Suply voltoage too low, ( 1 volt is required , measured 0.9 volt ) ,, multimeter show 1,14 and 1,10 volt on pins of carprog)

Hello!
I bought J link version 9.5 and software version 6.40 . I downloaded the software from Segger web . Connected to the Internet and update firmware to the latest version itself . I have difficulty with the project settings . For older versions of the software, there is how to set up the program. I do not find info for this version. In the MCU section of the tagged zone I have data . Do I write these data or bring itself ? Currently J link and Carprog are not connected and this section is empty to me. The other thing that bothers me is Target Power Supply .A things okay?
Thank you!
