Hi,

After flashing my test app into the TC397XX step B on the TFT board, the free Hightec debugger and the Infineon MemTool can't connect anymore. When powering up the board, the ESR0 LED flashes very briefly, and the backlight of the TFT display switches on. After approx. 0.5s the backlight goes off and the ESR0 LED turns on permanently.

Also tried to keep the reset button pressed during powerup, and only releasing it after clicking connect in the tools. This resulted in partial success. Without the trick, I get this errors in MemTool:

Message from component 'IMTMemtool' :
Can't connect to Target

Message from component 'Controller0.Core0.Tc2CoreTargIntf' :
Can't connect target !

Message from component 'Controller0.Core0.Tc2CoreTargIntf' :
Can't connect target device via DAS !

With the trick, I get only this:

Message from component 'IMTMemtool' :
Can't connect to Target

So something changed.

Any ideas what's happening and how could I regain control over the MCU?

The image that was flashed did not cover the UCB or any "sensitive" regions. It only has data in the 0x80000000-0x80019fff region. The startup code is obviously broken, the cores can't boot properly.

I only have the on-board debugger on the TFT kit and the free tools. Is this a known issue and would Lauterbach help?

Thanks, Ferenc

Hi vjalle,

I attached my .wsx file, DAS and UDE version is in above screenshot. I am using onboard miniWiggler which has a USBUART bridge chip onboard. COM5 is my USB port to communicate with the miniWiggler. Triboard TC397 is with default settings. Maybe you could change a new board to try. Or if you have a socket onboard, then you could change a MCU to try.

Dear Vjalle,

Have you used ADS to try? The App Board has onboard miniWiggler, so you can use USB cable to connect it to PC, and use ADS to debug it.

The ADS has DAS inside, the link is in below:

Hi DW,

Thanks for looking into this issue. Unfortunately, it did not work:

Error creating session
The debug instrument IO could not be initialized.
The GDI debug instrument provided the following error message.
An internal error has occurred.

I believe, all the tools I tried are using DAS, and probably failed in the same / similar way. Any idea what should I try?

Hi vjalle,

I am not sure if it's a software or hardware issue. Generally, if doesn't flash UCB blocks, the software will not impact the debug port.

Or could you send your software to me for test on my TC397 Triboard?

Hi DW,

Added the elf file in a zip. The linker also produces an s19 file. That I analyzed with srec_info to make sure that there is no data at the UCB. The srec_info tool output is as follows:

As you see there is nothing at the UCB. My feeling is that the MCU starts booting and then does something that the debugger does not like. Probably in that 0.5s window before entering the permanent reset state a good debugger with proper configuration should be able to connect.

I know that the __start_tc1 .. __start_tc5 functions are not called properly, because in the Tasking 6.3r1 compiler they're called __start_tc1_no_vtc, and or Os produced the old calls (without _no_vtc). They were redirected to endless loops. My assumption was that the cores stuck in infinite loops I'd see with the debugger. But can't connect anymore to debug it.

I'm curious how it works for you. Hope that it won't kill your board too...

Hi DW,

Did you manage to test it? Any ideas how could I recover access to my board? I need help with it as I don't seem to be able to fix it. Thanks.

Ferenc

Hi vjalle,

I have used UDE 2021 to download your .elf to my Triboard TC397, and then press PORST button, then I programmed .elf of my LED demo, and programming successfully. Then I press PORST button again, and see LED blinking.

That means my .elf works again, and your .elf doesn't interference my .elf.

C:\Program Files\pls\UDE Starterkit 2021

By the way, UDE 2021 is free software which you can download from below link:

Hi DW,

Basically the same symptoms, no luck. My board is in continuous reset (ESR0 illuminated), and UDE can't connect in this state. If the board is powered up with reset pressed, and I only release the reset button after clicking connect, something happens, typically this:

Error, Core0, Tc2CoreTargIntf, Can't connect target device via DAS !

Warning, Core0, Tc2CoreTargIntf, Failed to determine user application running state ! Assume still running

There were 2 connection attempts without the reset trick, and a 3rd one during reset. The board entered permanent reset after the 3rd attempt so in reality it did not connect.

Note the PSPR/DSPR failure. If I disable initializing PSPR/DSPR in the target config, and/or disable reset and select "break running application", the connection goes through. I can see the memory content, assembly listing (correct). However, when trying to single step the app, the board immediately goes into permanent reset again and the debugger disconnects. In the flash programmer the memory is not ready, all buttons are greyed out. Clicking the enable box results in yet another error message. If reset was disabled, it explicitly says that flash programming is not possible without reset. If reset was enabled, there is no further info and the details button is greyed out. So it did not work...

Are you using the integrated debugger (mini wiggler?) on these boards with DAS? Which DAS version? Or an UAD device? Maybe could you send me your UDE workspace? It seems that all debugger frontends are using DAS and suffer from the same issue here...

Thanks and best regards, vjalle

Hi vjalle,

I attached my .wsx file, DAS and UDE version is in above screenshot. I am using onboard miniWiggler which has a USBUART bridge chip onboard. COM5 is my USB port to communicate with the miniWiggler. Triboard TC397 is with default settings. Maybe you could change a new board to try. Or if you have a socket onboard, then you could change a MCU to try.

Hi DW,

Still the same, your workspace works in the same way as mine. Tool versions are identical (just updated DAS to 7.3.7).

When connecting with the reset trick, I can even see the SFR and switch on the LEDs by configuring the IOCR register through the debugger. I can see the disassembly list, set the PC and other core registers. However, when attempting to single step, or click the "Enable" checkbox in the flash programmer, the ESR0 LED immediately lights up and the debugger disconnects. In the target setup I have to disable reset and PSPR/DSPR init, otherwise the same happens directly after the successful connection.

Btw this is the KIT_A2G_TC397_3V3_TFT, not a Triboard. The MCU is soldered, not in socket. Will play with it a bit, open a ticket with PLS, and try to get hold of a Lauterbach.

And then it's time to give up and get a new board, I guess. Hope that won't be bricked so easily. Thanks for all of your help with this issue! Should you have any idea what could have gone wrong, let me know. Probably from the registers it's possible to figure something...

Best regards, vjalle

The root cause was that the STBYEV/STBYEVEN fields of  SCU_PMSWCR1 were written with wrong content by the MCAL. After commenting out that write the issue does not happen anymore.

Otherwise the MCU executed some further code after the write, and then entered the permanent reset state, where it was insensitive to even PORST. Only a power cycle helped, and debuggers could only connect in the time window between restart and executing the write to that register.
