We have a WEC7 OS design that is working well for the AM3354 processor. We recently changed to an AM3358 processor and are seeing large delays in some of the display routines, mainly related to refreshing the screen when selecting items from a listbox. We are running managed VB.Net code.
Does anyone know if there are any changes necessary to the OS when using an AM3358 vs. AM3354 processor? Our OS and .NET application are stored on an SD card. I can change the SD card from a system that has an AM3354 and it runs smoothly, I can take the same card and put it in a system that has an AM3358 and it has the delay.
The 3354 is running at 800Mhz and the 3358 is running at 1000Mhz. Boot times are faster on the 3358, which confirms the system is actually running at the faster speed, so why is the screen refresh slower? I'm assuming that I need to change something in the OS related to the 3358 processor, but I can't seem to find anything.
