Hi! I created a my custom IMX8MM board with DDR4. All DDR4 tests passed successfully in Configuration tools for IMX.
I am trying to make a u-boot for my board by Yocto. I take an IMX8MM_DDR4_EVK as starting point. But it is my first experience with Yocto.
Which files and where should I change or/and add to layers? It looks like I should change the Device Tree and config file for DDR4.
Can anyone give me a hint?
Solved! Go to Solution.
pls download yocto bsp according to the enclosed file, you can find all of source code there
The same question for 3.2.1 Changing the DCD table for i.MX DDR initialization
I try to find mx6q.cfg
Also, step 6 says, what I should change SPL. Where I can find a guide?
Okay. When I do step 5:
Edit the machine configuration file with device trees listed in the KERNEL_DEVICETREE.
Below code from evk board:
Thanks. What do I need to change the device tree? Do you have some guides for this or tools? Appnote AN5125 acceptable for IMX8MM?
yes, this AN is available for imx8mm, what kind of DDR4 do you use?
