Hi, everyone!
When I use FreedomStudio debug sample code “global_interrupts”, the following error occurs:

I do not know how to solve this problem, Can you help me to solve it?
Thanks!

Are you sure you are using a project targeting the right platform? For example, if you are using the HiFive1, did you import the HiFive1 projects?

(The FESPI_WRITE_REG error makes it look like you’re pointint to the wrong openocd.cfg file, because it’s pointing to the wrong place for the flash bank command.)

Thanks for your reply!

I fix some FPGA configuration files of Freedom code and generate bit file, then put on Nexys4 DDR.

On the basis of this, I import the E31 Arty projects, and I fix the expected-id of .cfg file.

I don’t fix flash bank comand. I think Nexys4 DDR and Arty board flash bank should be same.If there should be fix with flash bank, can you give some suggestion, I don’t know how to fix it.

Thanks!
