Do you support development environment for NXP linux kernel version 4.9.88 about I.MX6 UltraLite?
Hello Yun Ryan,
The i.MX Linux BSP is deployed trough Yocto, which is not intended for development but rather for distribution.
There are a couple of third party solutions that support the i.MX6UL which you can find on the link below, like ARM’s DS-5 or IAR so you may contact them for more details and support.
I hope this helps!
