Flash FDS Error/Stopped by Vector Catch When Accessing Stored Data.

Thanks for confirming, I just had to make sure. But I'm afraid can't think of any other obvious explanations for why your FW behaves differently. I guess it could be some differences in the toolchain as we have confirmed that we are compiling the same source code.

Could you try to download and install SES from https://www.segger.com/products/development-tools/embedded-studio/editions/arm/, then see if you get the same result? I used SES v5.44 to build the hex file earlier.

I made a mistake, the example I ran was from the nRF5 SDK 17.0.2 folder and was ran within the folder. I was using the nRF connect SDK as well for a different project and confused the two, sorry.

You mentioned the toolchain manager to install the SDK, but that's only meant for the new nRF connect SDK. The nRF5 SDK (17.0.2) is distributed as a .zip file and does not require any installation.

If you haven't already, plase try to download and extract the nRF5 SDK 17.0.2 zip and then build the project from this folder. This will ensure that we build with the same set of source files.

I ran your hex file and it works correctly when I flash it to the device. So this probably means there is something in my SDK that is incorrect then? How should I go about troubleshooting this issue?

Yes, I didn't encounter the vector catch on first boot. I had left the getTime() function enabled and I also made sure the chip was erased before I loaded the application.

Attached below is the .hex file I built here. Please try programming it on your board and see if you still get the same result.

Thanks for looking into it! So you were able to erase the device memory completely and the program ran for the first time with the getTime function enabled? I double checked my SDK and I'm also running SDK 17.0.2 and installed it through nRF connect toolchain manager with nRF connect SDK v1.5.0.

I reinstalled the SDK and ran the program but I'm still getting the same problem where if I try to build to an erased device while getTime is enabled the cli doesn't work. I also checked the memory and nothing was written so even though getTime is called after writeTime writeTime breaks as well which I don't understand.

When I add a breakpoint to debug I get the vector catch error, and I tried with a fresh unedited flash_fds example adding a breakpoint above the cli_start() function to check how the memory was initializing but I get a vector catch here as well.

Hello,

I did not manage to replicate the vector catch on my end, nor spot any obvious coding issues, unfortunately. I copied your code into the flash fds sample in SDK 17.0.2 and ran it on a 52 DK. Below is the log output I got after a few startups.

Any chance that some of the SDK source files may have gotten modified on you setup? It may be a good idea to try again with a fresh SDK copy in that case.
