Looking for ThreadX project examples running on Intel Stratix 10 Dev kit

xin zhang 31

Hello,
I tried to port ThreadX on the ARM Cortex-A53 (HPS of Stratix 10 SoC) in single mode. I was not able to run the example. Is there any example projects or a guide what kind of changes to the the sample_threadx projects do I need to make, to get it run.
Thank you very much in advance.

Hello @xin zhang ,

For better clarification can you share the error message or challenges you saw after porting ThreadX? And what documents you have followed to do it?

Thanks

Hi @xin zhang

Start with a bare-metal "hello world" type example application from Intel that runs on the Stratix. Make sure that it runs correctly. Then just add all the ThreadX source code and ThreadX example application - keep in mind that you may have to call the same hardware initialization code in main() [the same function(s) the hello world example calls] before calling tx_kernel_enter.

The bare-metal "hello world" is OK
When running the ThreadX example application, the first problem is register ICC_SRE_EL3 cannot access, that is may be stratix S10 use GIC-400 which follows GIC v2, but I am not sure.
The second problem is after running ERET (to do the switch from EL3 to EL1) , all memory cannot access, and I should change SCR_EL3 and mask the NS bit, I don't know why.

You can run ThreadX in EL1 or EL3. Rebuild the library with the appropriate #define enabled.

I rebuild ThreadX with #define EL3 and refer to "DAI 0527A Bare-metal Boot Code for ARMv8-A Processor" for startup code, and it works fine. Thanks a lot.
