Jlink script and DCD for Colibri IMX6ULL

I’m developing RTOS and bare-metal application on IMX6ULL and i connect via Jlink. I need the Jlink script file or DCD data also to be able to configure ddr-ram and peripherals.
Now i got DDR data verification error through Jlink running log
also my application in not running. and i lost jlink connection if i run the application

Greetings @ahamza.

Unfortunately we don’t have these resources for the Colibri iMX6ULL nor we support RTOS and bare-metal applications on the Cortex-A processors of the Colibri iMX6ULL directly.

I suggest you to contact SEGGER directly. I’ve found some interesting topics such as this: https://forum.segger.com/index.php/Thread/4943-SOLVED-J-Link-cannot-connect-to-i-MX6ULL-target/

Hi @gustavo.tx

I followed the Link you shared and according to this : https://wiki.segger.com/IMX6UL-EVK
there are resistors to be soldered/de-soldered. Does the same practice apply for Colibri module? how to be sure that my module is ready for segger Jlink?

@ahamza,

You shouldn’t need to tweak with any resistors on the Colibri iMX6ULL.

U-Boot includes DCD data for the module, so this might be a good starting point: https://git.toradex.com/cgit/u-boot-toradex.git/tree/board/toradex/colibri-imx6ull/imximage.cfg?h=toradex_2020.07
