Hello,

I'm trying to program Infineon CYT2B73CAD_M0 MCU (TRAVEO-II) with J-Link (SWD) using the J-Flash GUI, however I'm met with an error “Selected data does not fit into selected flash sectors” (see attached image). I believe it could be because of the lack of a "SFlash" region/bank (range: 0x1700_0000 to 0x1700_7FFF) (see attached image as it only shows Code flash and Work flash banks but nothing beyond).

Additional things I attempted:

1) Manually added a flash bank from the GUI; I get the error: “ERROR: Could not find CFI compliant flash device”.
2) I tried with the following J-Link command string in a J-Link Script that I included in my J-Flash projec

Unfortunately, even with the above, J-Flash complains with the same error that the “Selected data does not fit into selected flash sectors”.

(NOTE that I'm able to *read* the memory with J-Link CLI though - see attached image)

Questions:

1) How do I configure J-Flash to add internal SFlash region for the MCU and be able to program it? Is there any J-Link configuration or script file you can provide which enables SFlash region for programming?
2) If not J-Flash, can anyone please help with a J-Link CLI command to program SFlash (if somehow that would work effortlessly)

Hello,

The problem has been resolved after I updated the J-Flash utility version. We were previously using J-Flash v7.88; after updating to v8.10k (latest), during project creation, we're able to select "Supervisory Flash" bank and able to seamlessly program it directly from J-Flash.
