Crashes without power reset

[Proton]

Hey.
If the device is repeatedly flashed without turning off its power (it does not matter if I program it through SES or nRFgo), it may start to malfunction or slow down. At the same time, it is not loaded by software, polling several sensors and transferring it to another device. Why do I need to reset the power supply? Is this a SDK problem? I have sdk version 16.0.0 for s132.

Hi

What exactly do you mean by malfunction/slow down? Is it the clock(s) on the nRF that slows down or what? The Build and Run function in SEGGER Embedded Studio should execute a reset should reset before flashing every time.

What project are you flashing onto the device? Is it the same firmware every time you flash the device with small alterations?

Please note that nRFgo Studio is obsolete and outdated. I would suggest using the nRFConnect Programmer application for programming devices.

Best regards,

Simon

By deceleration, I mean a long walk through the initialization code. Yes, Build and Run does a flash reset, but it appears to be incomplete. But if this happens with nRFgo Studio, then it's not about the reprogramming method. I noticed this on several projects, and you don't even need to change them, everything happens by itself. There may be a problem in the firmware s132_nrf52_7.0.1_softdevice.hex ?

Does this occur on development kits as well? It would be helpful if you could explain how to recreate and check for this on our side as well, so we can test this out on our end. Approximately how much longer does it take for the initialization code to run after X amount of "flashes" compared to normal, and what crash are you seeing exactly?

Can you try another SDK and SoftDevice version to see if the issue propagates there as well? Please check if SDK v17.0.2 and SoftDevice S132 v7.2.0 give you the same performance issues.

Best regards,
