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?
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
