Hi @juanppalacios , I used the original base overlay [GitHub - mariodruiz/Kria-PYNQ](https://github.com/mariodruiz/Kria-PYNQ.git), and some python code to reconfig the V\_proc and Pixelpacker IP. You can find the python code here: > [@Kria base overlay, mipi cam5c, how to change the ColorSpaceConversion?](https://discuss.pynq.io/t/kria-base-overlay-mipi-cam5c-how-to-change-the-colorspaceconversion/6545): > > Hi all, I am working on the Kria base overlay (mipi\_to\_display notebook). I am trying to store a gray image via VDMA (8bits/pixel, Y channel). Using the following code: videomode = VideoMode(1280, 720, 8) mipi.configure(videomode) frame = mipi.readframe() frame.shape # (720, 1280) I get a gray image but, looking at the pynq code I see that pixel data is just written with the B channel. The reason is that v\_proc\_sys IP is configure to bypass the BGR pixels coming from the demosaic/gamma pi… In addition, in the following post you can find the workaround of a little bug in the overlay: > [@Kria base overlay BUG?](https://discuss.pynq.io/t/kria-base-overlay-bug/6693): > > Hi all, my problem is related to Kria KV260 & Base overlay ([GitHub - mariodruiz/Kria-PYNQ](https://github.com/mariodruiz/Kria-PYNQ.git)) & Vivado 2022.1. Taking a look at the MIPI of the base project, there is a Subset Converter to swap the channels. Input (MSB to LSB): R1 B1 G1 | R0 B0 G0 the swap is defined as TDATA remap string: tdata[15:0], tdata[23:16], tdata[39:24], tdata[47:40] Output (MSB to LSB): B0 G0 R0 | B1 G1 R1 So, it produces a swap between channels but also beween pixels. This can be seen in the … Regards --- _[View the full topic](https://discuss.pynq.io/t/kv260-read-mipi-frame-stuck-on-dma-help/5347)._
