Hello,

Your code is try to toggle GIOB_1 rather than GIOB_2:

gioSetPort(gioPORTB, gioGetPort(gioPORTB) ^ 0x00000002);

Your code looks fine, and it should work. Can you please try a large value compare 0? for example 1000 (1second). 37ms may be too small to see the blinking, the LED may looks like ON or OFF all the time.

B.M. probably missing gioInit() which brings the io module out of reset

OR set

gioREG->GCR0 = 1U;
