Booting from i.MX6UltraLite Evaluation Kit SD Card

[jiangshan_wei]

   I am evaluating processor i.mx6UL, plan to use ThreadX OS + IDE IAR, now purchased DEV board"i.MX6UltraLite Evaluation Kit" for evaluation. But all samples for flashing image to SD on DEV board are linux, where can i get doc/support/samples to  flash ROTS image and boot it via SD card on board i.MX6UltraLite Evaluation Kit.

Hi ken

one can try i.MX6UL MCUXpresso SDK for i.MX Cortex-M (sorry ThreadX is not supported by NXP)

https://www.nxp.com/webapp/Download?colCode=SDK2.2_iMX6UL_WIN&appType=license&location=null 

Best regards
igor

One more info: I am using MFGTool to flash SD Card. please find the ucl2 content as below:

<LIST name="SDCard" desc="Choose SD Card as media">
<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6ul%6uluboot%_sd.imx" ifdev="MX6UL">Loading Sdk20 U-boot</CMD>

I setup all (convert the IAR binary file to image file.....)as pdf "Getting Started with MCUXpresso SDK for i.MX 6UltraLite Derivatives" , plan to start application by mfg tool. but i get below message "

hi igor,

   Thanks for the link, i am looking at it. And will mark it correct once I get it work.

   One more question,  I read the U-boot doc, it say, U-boot support linux, vxworks....  and Threadx is not in list. So, do i need to customize current available u-boot to support Threadx OS booting?  thanks!
