"Invalid Parameter Error" when programming S110 SoftDevice to nRF51822 with nRFgo studio

[riceman0]

(this is duplicate with a support case I just opened... I hope that's okay.)

Hello, I am setting up a new laptop (our development machine caught a virus) and have installed nRFgo studio and am using it to install a SoftDevice onto a target nRF51822 (QFAA variants).

It seems like the SoftDevide programming always fails with an "Invalid Parameter Error". This seems to happen on a variety of CPU targets (always nRF51822) and softdevices (have tried 5.2.1, 6.0.0 alpha, and 6.2.1).

I have tried "Erase All" first, it doesn't help.

Further, when we try to upload to a target with a working SoftDevice/Application on it, the error seems to delete both the soft device and the app from the target, and we are dead in the water.

Can you please advise troubleshooting steps for this very vague error message?

Thank you.

@riceman0: I have the same suggestion as with Vidar in support portal. The new release of the nRFGo Studio, v1.20 is not backward compatible with older Softdevice. We will fix this in the next release of the nRFGo Studio.

In the mean time please use nRFGo Studio v1.19.

Hello, I try install the Studio v1.19 with the Tools but it comes out an error: nrfjprog.dll is not correctly installed. Please run the nRF Tools installer to install the newest version. So I try to install the Tools v1.20 but I remains the Studio v1.19 but it can't work. How to solve this problem

Hi Horiebin, I tried here and also have an issue with the v1.19. Seems that there is a incompatibility between nRFGo Studio v1.19 and nRFTools (all version). However there is a workaround for that. What you need to do is:

• Uninstall nRFTool, nRFGo Studio
• Install nRFGo Studio v1.19
• Rename folder "nrf51" in C:\Program Files (x86)\Nordic Semiconductor to "nrf5x"

It should work after that. But if you don't plan to flash old softdevice, then you should use nRFGo Studio v1.20. Future release of nRFGo Studio should fix this issue.
