TDA2xxEVM: Errors when uploading software to EVE using a XDS560v2 debug probe

Harald

Hi,

I'm trying run the EVE starterware example edma_simple_eve on a TDA2xxEVM using CCS 5.5 and a XDS560v2 debug probe. I followed the upload sequence described in chapter 3.6 of eve_sw_starter_guide.pdf. It works fine when I use the EVE simulator 1.0.

When I upload the binary to the TDA2xxEVM I'm facing errors:

ARP32_EVE_1: Trouble Reading Memory Block at 0xff776cdf on Page 1 of Length 0x1: (Error -1065 @ 0xFF776CDC) 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)

After uploading the application is stopped at main(). When I try to set a breakpoint I am facing the error message:

ARP32_EVE_1: Trouble Setting Breakpoint with the Action "Remain Halted" at 0x80001124: (Error -1065 @ 0x80001124) 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)

When I resume the application the breakpoint isn't reached and there are no messages on the console.

I'm using eve_sw_01_07_00_00.

Any suggestions will be much appreciated.

Regards,

Harald

Hi Harald,

I will forward your question to the Vision SDK experts in TI and update the thread as soon as I get their feedback.

Hi Harald,

A quick question from the software experts: Are you initializing your board with the gel files for the EVM?

Hallo Yordan,

I am a colleague of Harald. We are working with Vayu EVM and Yes we are using gel files from EVM.

Hi,

Just to clarify, you say you're using Vayu EVM, but which SoC is on your board, because TDA2x device is different than DRA7xx & OMAP57xx devices.. thus Starterware code might not work on your board (at least not without modifications).

Best Regards,
Yordan

Hi Jordan,

We are working with Vayu EVM which has TDA2x SoC. We are using EVE starterware 01.06.00.00 from Vision SDK 2.3.

Therefore we thought that it should work. Please let us know if we are wrong.

It should work.

Hi Yordan,

But we have problem in loading the binaries to EVE core. When we try to load the binaries, we get the error message as mentioned by my colleague in his original post.

Anshul, Harald,

As I said, I've contacted the Vision SDK experts, those were just additional questions, to provide more info for your query. I will update the thread with their feedback, as soon as I get one.

Best Regards,

Yordan

Hi,

I think I found the cause of this problem! :)

These error messages occur whenever the view "Variables" is active and one of the variables is a uninitialized pointer pointing to a memory area which is not mapped by the MMU. CCS tries to read the data at the pointer and it will fail.

In my case it happened after loading the binary when the application stopped at main() because all local variables were not initialized. But it also happens during debugging if I want to inspect the variables an one of the pointers points to an unmapped location. I could reproduce this issue with emulation package 5.1.600.0.

Once this problem happened debugging is not able anymore because either CCS or the JTAG emulator or the target is in an error state. The debug stession has to be terminated and restarted to continue debugging. Im my opinion, this is a bug and should be fixed.

Yordan, can you forward this to the responsible engineers, please?

Thank you in advance!

Best regards,

Harald
