Where are you probing the P2_0 signal? What header? Or are you probing the pad where the Ethernet chip once was (you said you removed it)If you look on the RSK schematic, IC29 is a pin multiplexer, and...

On the RZA1 RSK dev kit, we removed the ethernet chip and we were able to use the ETH_IRQ as IRQ6 by pinmuxing pin P4_14 in the kernel board file, board-rskrza1.c:r7s72100_pfc_pin_assign(P4_14, ALT8,...

The reason for the delay is that while the SPI driver is waiting for the transfer to complete, it puts that kernel thread to sleep. When the transfer finishes, the interrupt routine wakes up the...

From a technical standpoint, the VDC5 can drive a WVGA display (800x480), but only use a smaller frame buffer (like QVGA or something). You would just see a smaller image on the bigger LCD.Basically,...
