Hi,

[quote user="hebsud"]Are there specific changes required to make a SSD1309_128x64 OLED work with the SSD1306 driver and glue code., to get the lvgl application running on the nrf5340DK?[/quote]

You could start by looking at this blog which describes how this can be done for SSD1306.

Best regards,
Dejan

Thanks for the response Dejan!

Trying to get a Hello World app working using SSD1309 SPI OLED.
Are there specific changes required to make a SSD1309_128x64 OLED work with the SSD1306 driver and glue code., to get the lvgl application running on the nrf5340DK?

With the SSD1309 pins connected to PI.GPIO, the OLED display, powers up but is showing garbage. (attached pic)
What is a recommended route to debug this further?

Hi,

[quote user=""]I had the nrf5340 DK working for a few weeks now, and while working with SSD1309 OLED peripheral, was trying out a simple display application. Couldn't get the display device initialized, but started Getting the following error[/quote]

Do you know which action on your side caused the error? How did you try out a "simple display application"?

but started Getting the following error:

Error: One or more batch tasks failed:
* 1050029771: Device error: Setting the debug port SELECT register failed while powering up sys and debug regions (Unknown Error in J-Link DLL (error code =-1)).

This might indicate that the debug port is unavailable. Please double-check device power supply and SWD lines, and that SWD isn't disabled (Generic)

Which command generated this output?
