matteo serva 26fe48f53d fixed driver lockup at channel 0 RX. The fpga firmware 
was using the smi address pins to determine which channel can write the complex_fifo.
The read side of the complex fifo is connected to the DREQ pin of the SMI interface on the raspberry.
The address pins on the smi interface are at logic 1 when no transfer is in progress.

This caused a deadlock condition: the SMI address pin is at 1, so the fifo cannot be filled, so the DREQ cannot be asserted and the SMI cannot start reading data.

updating of install script - consolidation udev into driver and adding to main install
 2023-06-05 06:18:30 +00:00
David Michaeli 603d4664ca 1. creation of device driver dir - loadable with "install.sh" file. 
2. creation of udev file loading for smi to load automatically with the correct permissions
3. firmware bugfix - negate 2.4GHZ I/Q ddr data
 2023-06-04 19:57:15 +00:00
David Michaeli 79d5ee11af Changes in IO utils. 
1. removed pigpio
2. moved to using gpiomem api for gpios
3. using spidev for soft-hard spi
4. updated the other parts of software.

note: tbd changes in the config.txt of spidev.
note: tbd moving out he kernel module to /etc/modules.d to be completely free of sudoing anything

firmware rx verification
 2023-05-31 14:11:47 +00:00
David Michaeli f97f960be6 added TX channel to the FPGA firmware. 
LVDS RX -> FIFO Slacks are borderline - need perform timing analysis on the RX FIFO IO (add pipeline?)
