I've installed notochord as a program on Debian linux on a Raspberry Pi 4 (no Rasp 3's available...); however, during init, I get an error:
bcm2835_init: gpio mmap failed: Cannot allocate memory
I downloaded the current bcm2835 1.62 library which has a fix for Rasp Pi 4 for gpio.
I unzipped the tar file and put it in the notochord/lib folder, and I edited src/Chordata_gpio.h to change the include:
Then recompiled notochord:
scons -j3 debug=1
But running ./notochord still returns the init error. Is there a fix for Raspbery Pi 4?
