"Unable to access device memory" error

Other Parts Discussed in Thread: TCI6630K2L

I have a EVMK2L board. I tried to run some programs on the board, and it gave me the following errors:

"

Trouble Writing Memory Block at 0x2ee4b0 on Page 0 of Length 0x1e0: (Error -1190 @ 0x8000) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.232.0)

"

I am using CCS5, and the targetConfigs is TCI6630K2L. I compiled for little endian and ELF output, and left the linker command file blank.

I actually encountered this error before, and the way I fixed it is to pick a linker command file. Since there is linker command file for TCI6630K2L, I used C6678.cmd as the linker file and it worked.

But this time when I used C6678.cmd file, I got another error which indicates that the linker command file is incompatible:

"Trouble Reading Register ControlRegisters_CSR"

So I have two questions:

1. What is the correct linker command file that I should use for TCI6630K2L, and where can I get it?

2. Some TI engineers on this forum said that you should let the emulator automatically choose the linker file, but how? Apparently if I left the linker command file blank, the program cannot access the correct memory address. So please tell me how to fix this.

Thank you!

    Hi,

    Memory map for TCI6630K2L and C6678 both device are different. so C6678 command file does not work on TCI6630K2L device.

    Please take a look at below wiki link and refer TCI6630K2L device Memory mapping table on data manual to create a command file.

    Refer MCSDK example project command file: C:\ti\pdk_keystone2_3_01_03_06\packages\ti\platform\evmk2l\platform_test\

    Have you using TI MCSDK example for your testing? If yes, share the project detail.

    Thanks,

    Thanks, Ganapathi. I used the example that you gave me and did some minor modification, and now it is working.

    I am building FFTW for EVMK2L, and trying to run a simple example with the library. And this is the last step to run the code through the emulator.

    Thanks a lot.
