Hi guys,

I am in the process of creating a new environment for an Incurcit programming application. For this I have to flash a "XMC1302-0064" with an "Infineon XMC Link Flasher" with a .hex file from our customer. As programming software I use the "Infineon XMC Flasher" and the drivers from SEGGER J-Link Software 7.84d (latest).

My problem is that I can not connect to the microcontroller.

Error message: com.infineon.XMCFlasher.DebuggerExceptions: Error retrieving BMI value

I found out that the microcontroller is by default in a "wrong" BMI for my application.

See: https://wiki.segger.com/Infineon_XMC1000

I tried the solution for my flasher (with DAVE software), but I can't read or change the BMI either.

We already have an "old" programming environment that works perfectly. I changed programmers and the programmer from the old environment also works perfectly on my table. The new programmer did not work in the old environment. I have a second new programmer, but that doesn't work either. So it looks like the new programmers are a little different than the old ones. (I used the same MCU and the same board).

I already read the other topics about the BMI problems, but it looks like the most common solution is to connect 1.3 to SWD and 1.2 to SWCLK to connect to the MCU. But in my case this is not the solution, because it works if I replace the new programmer with the old one. I think is has something to do with the programmer.

When I connect the old programmer to the PC, I get the suggestion to update the firmware on the programmer, which of course I refuse. But this means that there is a different software on the old programmer.

Does anyone have any ideas on how to proceed? Is there perhaps a way to downgrade the software on the programmer?

Thanks in advance, Maddin

A XMC program can be set to run in either the cached or non-cached Flash memory space. Our application runs in the cached address space which allows it to run faster. We also have an update possibility within the application.

I am not sure if it is OK to use the cached Flash addresses during the re-programming. Does it make any difference which address space is used.
