A while ago, when working with Claudio on the IGEPv2 WIFI issue, we noticed that the screen went black when writing something to the SD card. This happened when we created a new file via the command line or sending a file via qconn to the SD card. We did not have the time to look at it and we did not know what caused it but Fabio Fattori solved the issue in the meantime. The solution can be found on Foundry27, the community site of QNX by following this link. The solution will be included in the next release of the IGEPv2 BSP.
More updates on the IGEPv2 development will be posted on ATS TechLab.
