Run application using OCRAM in imx6dl sabresd reference board

[winstonjacob]

I am using imx6dl sabresd reference board, and I want to run a sample application using OCRAM, and I referred the link mentioned below.

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/iRAM-OCRAM-i-MX6-SDK-Application/ta-p/11...

I compiled the imx6 sdk  and I got iram.bin and iram.elf, then flashed the u-boot image as well as iram.bin to sdcard, then I booted the board, and I executed the command in u-boot prompt, and I mentioned the log here, please verify and help me to run the application in OCRAM memory.

Hi Winston

in general one can try to load bin file using mfg tool as described on

https://community.nxp.com/t5/i-MX-Processors/Loading-Sample-SDK-on-IMX6-SABRE-board/m-p/320466

change ucl2.xml :

"SabreSD-SD" profile:

<LIST name="SabreSD-SD" desc="USB SDP">
<CMD state="BootStrap" type="boot" body="BootStrap" file ="test.bin" >Loading image</CMD>
<CMD state="BootStrap" type="jump" > Jumping to image. </CMD>
<CMD state="Updater" type="push" body="$ echo Load Complete!">Done</CMD>
</LIST>

Mfg tool can be found on

Thanks for your immediate reply @igorpadykov ,

       Using mfgtool I can able to load the sample application which NXP provided (RVDS 3.1 MX6DQ_SDP_LED.ZIP.zip) , but in this sample app I have to do some modification and I have to cross compile and execute,

RVDS 3.1 MX6DQ_SDP_LED.ZIP/MX6DQ_SDP_LED$ arm-linux-gnueabihf-gcc main.c -o led.bin

      If I cross compile using the above command, I am able to generate a bin file, but that bin file I am not able to load via mfgtool, while loading mfgtool throwing error. Can you please give me the compiling steps for RVDS 3.1 MX6DQ_SDP_LED.ZIP.zip application.
