TMS570LC4357: Issues with running example to configure EMIF to write and execute from SDRAM

Robin Y.

Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Tool/software:

I'm trying to build and run the HALCoGen example to set up the TMS570LC43 HDK EMIF to write and execute from SDRAM and I'm seeing a DataEntry error when I try to step into the function stored in SDRAM after the instruction pointer jumps to it. I've attached a screenshot from the CCS debugger as well as the MPU configuration in HALCoGen. Any help would be appreciated.

Hi Robin,

Can you please refer below attached my example. It is working without any issues in my HDK board.

Thank you for the example code, I was able to build and load the project you attached and it does work. My use case, however, is trying to run code from SDRAM that was built using a different toolchain (ARM GCC) that I can flash onto the SDRAM. I'm trying to figure out if I can edit this project to jump to a start address that I know the value of in the executable that I'm loading onto the SDRAM. I tried creating a function pointer to the start address and execute that, but I'm getting a data abort exception.

Hi Robin,

Is it possible for you to share your project for quick debugging at my end? If you want, you can also send me through private chat.
