Kadalia commented 8 years ago

Hello, got the error "Write to CapeMgr slots failed: ENOENT, no such file or directory" with a simple script.

I dont know if it's a problem, when i do ls /lib/firmware/ i get : dra7-ipu2-fw.xem4 dra7xx-m4-ipu2.xem4 vpdma-1b8.bin

Beagle bone installed with debian uname -a : Linux beaglebone 4.1.13-ti-r38 #1 SMP PREEMPT Thu Dec 31 23:38:01 UTC 2015 armv7l GNU/Linux

Thank you ! Philippe

bone.js fs.writeFileSync(slotsFile, name, 'ascii'); (near line 200) rises an error ENOENT, no such file or directory but the file exists !!! debug(fs.existsSync(slotsFile)); return true !!!!!!!! if i comment onWriteSlots(err2); seems to work ! heu ... I do not understand !!!

What is your original function call? Can you paste code here?

adityapatadia commented 8 years ago

Btw, the error is that it found slots file but it is not able to find .dtbo file for cape-universaln inside /lib/firmware folder. I suggest u re-install latest debian from link given in readme.
