Execution profiling with NRF52832 for Filesystem using PCA10040?

[beadon]

We are incorporating a filesystem for NAND flash driven by the NRF52, but we are running into performance issues using littlefs and want to do deeper troubleshooting.  From this Segger article we see there is a hat available for the Nordic Dev kit : https://wiki.segger.com/Tracing_on_Nordic_Semiconductor_nRF52832 model number Nordic RF52 PCA10040 V0.9.0 .  Where can we get something like this to continue troubleshooting ?

Thanks !

Hi,

The adapter you linked to is not available for sale, unfortunately. You can find the schematic and hardware layout for it here link if that helps. I would suggest that you try the SystemView application from Segger and see if it's something you can use. It uses the regular SWD lines for communication, so it does not require you to use a high-end Segger debugger.
