Hi,

We are working on imx6ul board (MCIMX6UL-EVK). We want to run freertos on the board which has cortex A7 processor. We have downloaded the freertos source code and tool we have is IAR. But there is no demo project for imx6ul. So we have chosen CORTEX_A9_RZ_R7S72100_IAR_DS-5 demo and compiled on IAR workbench. But there are some lowlevel initialization functions (chip and board specific functions) in cstartup.s file. While execution the debugger is throwing the error (outside memory linked address …please see the attachment). I think we are getting this error because the project is created for a different board (Renesas board). Could some one please let me know how to initialize the hardware for imx6ul.

Thanks
Atma

Find a non-FreeRTOS demo application that targets the hardware you are using (I suspect IAR will have one themselves) and copy the init code from that. If you run Renesas init code on a Freescale/NXP board then I would expect anything that touched hardware outside of the Cortex-A core itself is going to give you an issue as it won’t exist on your part.

??? The first thing to do would be to see if IAR provide code
themselves, do you want me to do that for you? Really? How is it
easier for me to stop what I’m doing to do this for you, then report
back to you, rather than for you to do it yourself?
