Still having issues with driver failing to load. #61

Closed synaption closed 1 year ago

synaption commented 2 years ago

I was hoping that something would happen to fix this issue but I finally got around to building the latest version of the driver and I am still having the problem where the driver does not load about half of the time. Below is my dmesg.

sudo insmod /home/pi/nrc_pkg/sw/driver/nrc.ko  hifspeed=10000000 spi_bus_num=0 spi_cs_num=0 spi_gpio_irq=5 spi_polling_interval=0 fw_name=uni_s1g.bin auto_ba=1 sw_enc=1 listen_interval=1000

synaption commented 2 years ago

nrc_simple.ko seems to load reliably.

synaption commented 2 years ago

a solution that would allow me to rmmod and load again without rebooting would be sufficient for my purposes. Currently I get the below error. 

$ sudo rmmod -fv nrc 
rmmod: ERROR: could not remove 'nrc': Device or resource busy
rmmod: ERROR: could not remove module nrc: Device or resource busy
synaption commented 1 year ago

Being carful to rmmod the driver before shutdown alleviates this problem in my current circumstances. I am guessing it has something to do with trying to load the firmware when it is already loaded.
