SPI using legato issue on wp76xx



I am using example from:

I have uploaded the spi module :

insmod /mnt/legato/system/modules/spisvc.ko

root@swi-mdm9x28-wp:/data# lsmod | grep spi
spisvc 894 0 [permanent], Live 0xbf000000 (O)

root@swi-mdm9x28-wp:/data# ls -l /dev/spidev1.0
crwxrwxrwx 1 root root 153, 0 Nov 29 16:27 /dev/spidev1.0

  • I modified on the example code to use spidev1.0

code is running OK but I see nothing on SPI lines.

however when I am using a default Linux SPI utility I can use the SPI, issue read and write

please advice
