I test General Purpose Outputs MRAA Pin numbers 35 to 41, 45 to 47, 52 and 53. I connect 1K resistor and LED for output testing. I take below reference command for testing above all pins. echo 77 > /sys/class/gpio/export echo out > /sys/class/gpio/PC13/direction echo 1 > /sys/class/gpio/PC13/value echo 0 > /sys/class/gpio/PC13/value. I faced issue in MRAA Pin number 35 and Pin number 38. Output not getting on and off for MRAA Pin number 35 and Pin number 38.

I checked adc peripheral using cat /sys/bus/iio/devices/iio\:device0/in_voltage6_raw command. I give Analog volt using CA71 yokogawa universal source but I do not get consistency in ADC reading. Please, suggest us any alternate way to get good accuracy in ADC.

When I followed the steps for the cross compile the hello_board c code on this link https://developer.ruggedboard.com/g5-system-development-guide/host-setup and tried to execute the hello_board on the rugged board then it gives below error. root@rugged-board-a5d2x-sd1:~# uname -a Linux rugged-board-a5d2x-sd1 4.9.151-linux4sam_5.8+-04823-gab4590e #1 Tue Mar 31 08:57:52 UTC 2020 armv7l GNU/Linux root@rugged-board-a5d2x-sd1:~# ./hello -sh: ./hello: not found root@rugged-board-a5d2x-sd1:~# Logs on Host system: upesh@upesh-Lenovo-Z50-70:~/c_project$ cat hello.c #include <stdio.h> int main() { printf("Hello board!!\n"); return 0; } upesh@upesh-Lenovo-Z50-70:~/c_project$ arm-linux-gnueabihf-gcc hello.c -o hello_board upesh@upesh-Lenovo-Z50-70:~/c_project$ ls gpio_toggle.c hello_board hello.c test1 upesh@upesh-Lenovo-Z50-70:~/c_project$ sudo cp hello_board /var/lib/tftpboot/ File details: upesh@upesh-Lenovo-Z50-70:~/c_project$ readelf -h hello_board ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: DYN (Shared object file) Machine: ARM Version: 0x1 Entry point address: 0x3fd Start of program headers: 52 (bytes into file) Start of section headers: 6996 (bytes into file) Flags: 0x5000400, Version5 EABI, hard-float ABI Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 9 Size of section headers: 40 (bytes) Number of section headers: 29 Section header string table index: 28 upesh@upesh-Lenovo-Z50-70:~/c_project$ Logs on Rugged board: root@rugged-board-a5d2x-sd1:~# tftp -r hello_board -g 192.168.1.101 root@rugged-board-a5d2x-sd1:~# ls hello_board root@rugged-board-a5d2x-sd1:~# chmod +x hello_board root@rugged-board-a5d2x-sd1:~# ls hello_board root@rugged-board-a5d2x-sd1:~# ls -ll -rwxr-xr-x 1 root root 8156 Jan 1 01:04 hello_board root@rugged-board-a5d2x-sd1:~# ./hello_board -sh: ./hello_board: not found root@rugged-board-a5d2x-sd1:~# Please help to provide the solution for it.
