GPU LED blinking - Raspberry Pi Forums

-

lots of baremetal booting vc4 , switching arm on , doing stuff on arm.

opencl on vc4 has got me thinking gpu/qpu

has blinked gpio led qpu code?
activity led under vpu control on boot?

been wondering if qpu's used real time controllers
nanokernel's in qpu?
have not seen qpu specific timers, vpu's have any?

assume threedx os running in 1 vpu after bootcode.bin running.
leave other vpu free, unless threadx running multicores :o

dom, engineer @ pi towers, said qpu cannot access peripheral bus: viewtopic.php?f=72&t=128309. it's unlikely think.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
