Trying to compile adxl345 as a module in bbb but get error

[Mrigendra Chaubey]

Hi all,

I have downloaded a debian image

Debian 8.7 2017-03-19 4GB SD LXQT 

I have attached a adxl345 accelerometer, and with user space tools its working fine.

Now I am trying to attach a kernel driver i.e in adxl345. I put the source files in 

/home/debian/Desktop/adxl345

and issued make.

I get this error

root@beaglebone:/home/debian/Desktop/adxl345# make

make -C /lib/modules/4.4.54-ti-r93/build M=/home/debian/Desktop/adxl345 modules

make[1]: *** /lib/modules/4.4.54-ti-r93/build: No such file or directory.  Stop.

Makefile:13: recipe for target 'default' failed

make: *** [default] Error 2

I checked 

root@beaglebone:/lib/modules/4.4.54-ti-r93# ls 

extra    modules.builtin modules.devname  modules.symbols.bin

kernel    modules.builtin.bin modules.order

modules.alias    modules.dep modules.softdep

modules.alias.bin  modules.dep.bin modules.symbols

there is no build directory. I tried to update kernel headers 

sudo apt-get install linux-headers-linux-headers-4.4.54-ti-r93

but it says

E: Unable to locate package linux-headers-linux-headers-4.4.54-ti-r93

How I am going to build the drivers?

Oh, it's there, run "sudo apt update" first to update your apt cache..
