Installed Segger Studio v4.12, nRF5 SDK(latest version), J-link, all under same catalog but into their own respective catalogs.
First, if I open blinky catalog and choose the .hex-file, then drop it to the j-link drive, the nRF52840 board starts downloading and when finnished the diodes starts blinking in a pattern, ok!
Second, I click on the blinky project file(dont remember the name but has an eye icon to it), the project loads, building and running goes fine, but no downloading into the nRF52840 board ?
Third, I like to pick the nRF5 SDK project from Segger Studio, File ->Project Import or like that. But when clicking into the catalog where the project-file was located earlier, it appears no files.
Fourth, there are no text files explaining the different example files in nRF5 SDK, what they really do and what interaction can/must be taken to get most out of them
Fifth, I had problems installing "Packages" when setting up Segger Studio, if this could have any thing to do with some of my above problems ? se picture below
almost there now but still no "blinky" downloaded from SES "Build and Run". In the "Output" window there is just "OK" on each line. I also see some activity on the"download" LED when Debuginng and Runing, but the four LEDs dont blink as they should. Only LED 1 is stationary on.
Any idea ?
All GPIO's are high impedance after reset (thus all LEDs off), so since LED 1 is lit you have definitely programmed something onto the board.
Are you using the BLE Blinky Application example (from <SDK>\examples\ble_peripheral\ble_app_blinky\)? If so, that is expected. Then LED 1 will be lit solid until a central connects, and at that point you should see LED 2 lit. You probably want the simple Blinky Example (<SDK>\examples\peripheral\blinky\) which only blinks the LEDs instead. This is always a good start to see that programming works.
what do you mean by "central" ? think I use BLE Blinky. When I drop the .hex-file from the same catalog to j-link drive, the four LEDs start to blink in a certain pattern after programmed. Programming from SES, LED 1 is lit all the time, no blinking
The LEDs will not start blinking in a pattern when you use the BLE Blinky Application. This is for controlling/"blinking" the LED from a BLE central (see example documentation). You have to use the Blinky example to get the typical blinky behavior.
downloading works fine now from SES. But now I like to use some of the ANT example projects. Im told to install SoftDevice package before downloading the example firmware. I have downloaded and tried to install nRFgo Studio, but got some error messages. I can open the studio, but the explanation in the ANT ex. about how to download SoftDevice doesnt correspond with what I find inside the studio. I cant find the nRF52840 chip which is my target on the board.
Is this a common problem ?
I am glad to hear it works. Please create a new thread for as the last question is unrelated to the original one. Keeping separate topics in separate threads makes it easier for other users to navigate old questions and answers.
