Thanks Igor, I had a similar feeling. If you can remember the other patch let me know. I'm hunting for it now. I will definitely try again on Vanilla Kernel, I am switching hardware soon in the next version of my project, and want to start with a different pcap display anyway.

Hello, I am trying to switch from an older wheezy (lemaker) install to a newer Armbian Jessie install, (5.14 Armbian).By using the Legacy Kernel I can load ft5x drivers for the 5" PCAP Screen. So Far, everything is working normally except much faster and reliable. My Problem is that I can't read the analog voltage from my MCP3002 anymore using spidev python module. I have spidev and spi-sun7i in /etc/modules ls /dev/spi* /dev/spidev0.0 /dev/spidev0.1 dmesg | grep spi [ 1.202344] [spi-inf] Found 2 spi devices in config files [ 1.209170] [spi-inf] boards num modalias max_spd_hz bus_num cs mode [ 1.212928] [spi-inf] spi_board0 irq gpio not used [ 1.219895] [spi-inf] 0 spidev 12000000 0 0 0x3 [ 1.223651] [spi-inf] spi_board1 irq gpio not used [ 1.230615] [spi-inf] 1 spidev 12000000 0 1 0x3 [ 1.234711] [spi-inf] sun7i_spi_probe: sun7i spi probe [ 1.239335] [spi-inf] sun7i_spi_probe: spi0 dma type: normal [ 1.242909] [spi-inf] bus num = 0, spi used = 3 [ 1.247368] [spi-inf] sun7i_spi_probe: spi0 cs bitmap: 0x3 [ 1.255945] [spi-inf] sun7i_spi_set_mclk: spi0 source = sdram_pll_p, src_clk = 432000000, mclk 86400000 [ 1.261869] sun7i-spi sun7i-spi.0: master is unqueued, this is deprecated [ 1.268004] [spi-inf] sun7i_spi_setup: enter, bpw: 8, mshz: 12000000, mode: 3 [ 1.274193] [spi-inf] sun7i_spi_setup: enter, bpw: 8, mshz: 12000000, mode: 3 [ 1.282984] [spi-inf] sun7i_spi_probe: reuuimlla's SoC SPI Driver loaded for Bus SPI0 with 2 Slaves at most [ 1.292384] [spi-inf] sun7i_spi_probe: spi0 driver probe succeed, base f051c000, irq 42, dma_id_rx 24, dma_id_tx 24 If I try to use wiringPI: gpio load spi gpio: Unable to load spi-sun7i I've simplified my mcp3002 code to reproduce the error. import spidev s = spidev.SpiDev(0,0) s.max_speed_hz = 12000000 reply = s.xfer2([160, 0]) -------~> reply = s.xfer2([160, 0]) IOError: [Errno 22] Invalid argument However, the Exact same hardware Config on wheezy (3.4.103+) results in: import spidev s = spidev.SpiDev(0,0) s.max_speed_hz = 12000000 reply = s.xfer2([160, 0]) [0, 2] Anyone have an idea about why I keep getting the Invalid Argument? On the wheezy build, 3.4.103+ this code is functioning.
