Now I am testing GPi #3 with gz_test. I forgot if I have changed gz_test.c so that the GPCLK0 frequency is 9.6MHz, and after binary counting down 14 times, becomes 585.9 Hz.
I have configured GPi #1 and #2 as below.
1. GPi #1, GP #2 power off, so they will not crash with the SPI of GPi # which is being tested.
2. GPi #1, GP #2 JTAG jumpers are set to "run" mode, which means the JTAG signals are disconnected from GPi.
3. JTAG, SPI, and PWM/GPCLK0 cables are daisy chained. That means these cables connecting to GPi #1 and GPi #2 are not disconnected and reconnected and might cause wrong connection problems.
