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: [SOLVED] J-Link cannot connect to i.MX6ULL target - J-Link/Flasher related - SEGGER - Forum
Hi @gustavo.tx
I followed the Link you shared and according to this : IMX6UL-EVK - SEGGER Wiki
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: imximage.cfg « colibri-imx6ull « toradex « board - u-boot-toradex.git - U-Boot bootloader for Apalis and Colibri modules
