I’m writing a cross-platform application which works on x86 machines, but crashes with “Bus error” on the actual ARM hardware (Raspberypi 2) … … but runs without any problems in Qemu. I run this command to enable SIGBUS signal and notification in the kernel running under Qemu, bu…

C NET-SNMP Get and Set specifically via MIB Name, Not OID
I have written and am testing software for a generic SNMP client module in C as well as an implementation using this generic module. I am having trouble getting a get request to work by passing in a MIB name(e.g. sysDescr) instead of an OID(e.g. 1.3.6.1.2.1.1.1). I am successful when I pass in a character arr…
gcc: error trying to exec ‘cc1’ when cross-compiling
I downloaded toolchain from parrot Github, installed, now I am trying to crosscompile here with the following command line: here’s the error log: Answer You should use the arm-none-linux-gnueabi–prefixed toolchain in bin instead. e.g. instead of
How u-boot start instruction is found by ROM Code
I am trying to understand ARM Linux Boot Process. These are the things I understood: When reset button is pressed in any processor, it jumps to the reset vector or address, in case of ARM it is either 0x00 or 0xFFFF0000. This location contains the start up code or ROM Code or Boot ROM Code My query is how thi…
tcpdump error message “That device doesn’t support monitor mode”
Running Linux on a Xilinx ZCU102 development board. When using a 1000BASE-X & Tri-Mode Ethernet Mac. I can send pings out of the Ethernet port, but when I run tcpdump to try and show that packets are coming into the system… I get a strange error from tcpdump. Curious if anyone has any insight on thi…

cross compilation for ARM: error no such file or directory/command not found
I have written simple Hello world program and compiled it with gcc-arm-linux-gnueabi compiler. It compiles well but when i try to execute it on ARM machine it complains “no such file or directory”. I think gcc-arm-linux-gnueabi is for embedded Linux only due to e(mbedded)abi. Is it different from …

“Illegal instruction” when running ARM code targeting my CPU
I’m compiling a rather large project for ARM. I’m using an AT91SAM9G25-EK as a devboard running a Debian ARM image. All libraries and executables in the image seem to be compiled for the armv4t instruction set. My CPU is an ARM926EJ-S, which should run armv5tej code. I’m using GCC to cross c…
