KB 12:11 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: A CCS Debug issue occurred.: Yes, that's right.
I am planning to experiment only with the DSP part using CCS JTAG without ARM.
So, as mentioned above, the error occurs regardless of whether the kernel part is running, so it is not possible to work with DSP alone. Kyungguk Bok

JC 02:35 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: A CCS Debug issue occurred.: Hi, I feel in the dark about what you have tried and are trying to do. And what works and where you are stuck. If you followed the DSP Hello World, did it work as written? And you are now trying to update it to work without the ARM? Jonathan Cormier

What can happen if I set up my DSP project incorrectly?

This shouldn't happen. Unless you... Jonathan Cormier
KB 12:15 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: A CCS Debug issue occurred.: 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
JC 07:32 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: A CCS Debug issue occurred.: 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

KB 09:50 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: I have another question regarding EMIF.: 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?

KB 12:17 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: I have another question regarding EMIF.: 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...

isn't making sense to me. Jonathan Cormier

I have another question regarding EMIF.
Currently, we have performed an EMIF communication GPIO example using MDK.

From a DSP perspective, we proceeded by entering the phys... Kyungguk Bok

WE 07:14 PM MitySOM-AM62, MitySOM-AM62A, & MitySOM-AM62P Software Development: RE: AM62A module SODIMM pinout documentation error: Pal,
While going over the SODIMM pinout in our datasheet I noticed a couple more errors. We are working releasing a new revision to the datasheet but in the meantime the other issues are listed below:
