Is there another way to load the DSP?
I am using version 7.3.0 of CCS, and after proceeding with the build project, press debug (Scarab button?) or enter the debug window through Target Configurations. When you press the debug button,... Kyungguk Bok

As long as your willing to use u-boot on the ARM to load the DSP and the FPGA then I think this should already work. U-boot has to have configured the EMIF to sup... Jonathan Cormier

How are you launching the debug session? How are you trying to load the DSP?
If you click the Debug button (F11), it should build the DSP project and then load it over the JTAG. Jonathan Cormier

I have additional questions.
I would like to perform EMIF communication only with DSP and FPGA, without ARM.
If you proceed without fpga_ctrl.ko, does EMIF communication proceed without ARM?

Thank you for answer.
I'm still a beginner, so my questions may be basic.
If I input o_DBus<= Data in FPGA, will data be transmitted?
As far as I know, EMIF has an address and data, but the example above only has a CS address.

MW 11:22 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: I have another question regarding EMIF.

If you have the FPGA portion working by decoding the address to the FIFO using the base_module.vhd file, which generates a read strobe and an enable, etc., then for the DSP all you need to do is create a basic integer pointer and derefer... Michael Williamson

We are working on the SDK 09 release right now. This is built using yocto kirkstone and uses gnu 11.3 and bumps u-boot to 2023.01 and the kernel to 6.1. The release is supposed to be imminent though unrelated problems keep redirecting r... Jonathan Cormier

What is the recommended approach to toolchain management?
