Ok, I fixed my problem by changing the above line to:
I don't see any problem that needed fixing.
The problem is that without specifying the section attribute, when I ran my code, i2c_bus_num was equal to 0xFFFFFFFF.
static volatile unsigned int i2c_bus_num __attribute__ ((section ("data"))) = 0;
Is "data" the right section to use? Here's my lds file:
If you have to ask this question, then the answer is no, and better don't mess with things you don't understand.
What exactly is the "problem" you are experiencing? Did you read the documentation, especially section "Initial Stack, Global Data" in the README? Please let me know if there is anything in this text which is not clear enough.
That section doesn't address issues with global (static or otherwise) variables that need to be read prior to relocation.
