Hello, I compiled a module with a 4.19.66 kernel for Raspi. But installing doesn't launch the module. Manual loading the module to the system via sudo insmod gives error with symbol. In dmesg we can see couple of errors:

Hello, i setup to use the DW1000 chip with a direct connection to RPi4. Chip is on EVB1000 board. I have 2 boards. Both configured for channel 7, cfg->rate 2, cfg->pulse 2, get pcode 12. Im using iperf3 test program to test UDP connection between boards and best speed that I can achieve is 1Mbit. I want to have 2.5Mbit. Is there some tricks that will help me to increase communication speed?

hi,

linux kernal 4.9.x ptp_clock_info struct have no adjfine

Hi,

I have cross-compiled your driver for a Yocto-linux embedded device (with no errors).
However, when trying to send frames, I get an error (-22). Do you have an idea from where this could come ?

Bellow more details on the procedure and error :

1. I load the cross-compiled DW1000 module
2. Enable wpan0 interface :

ip link set wpan0 down
ip link set wpan0 address 76:dd:3c:55:1c:43:9a:aa
iwpan phy0 set channel 4 2
iwpan dev wpan0 set pan_id 0xCAFE
iwpan dev wpan0 set short_addr 0x0001
ip link set wpan0 up
iwpan dev

3. Send frames (ping) :

wpan-ping -a 11:22:33:44:55:66 -i wpan0

4. No frames are sent or received by my other device, and here is the result of dmesg :
