Hello all,
I have a AM3359 ICE v2 and I am using it to set up a working baseline for development.
I have gotten so far:
1) I have set up the host Linux development platform based on Ubuntu 18.0.4.
2) I have downloaded and installed the SDK for AM3359 on the host and run the setup.sh script.
3) I have deleted the SPI flash on ICE v2 and prepared a SD card.
4) I put a test program under the usr directory of the development board.
5) I can boot ICEv2 using the SD card, I can log in as root.
The test program is an empty main function as follows.
int main(void)
{
return 0;
}
This is its compilation information:

6) When I run it, it will report an illegal instruction error.
root@am335x-evm:/usr# ./Test.out
Illegal instruction (core dumped)
Ask me, why is this error reported? thank you very much.
