Compiler/CC3220MODA: usleep (1000000) is not equal to sleep(1)

Part Number: CC3220MODA

Tool/software: TI C/C++ Compiler

Dear TI support,

My application used usleep(1000000) with SDK 1.50 and it worked fine. After updating to SDK 1.60 it didn't seem to work. I played with the usleep number but it didn't help. Then I used sleep(1) instead of usleep(1000000). The sleep(1) worked. I am wondering if this is expected.

Thanks,

David

Hi David,

I can't explain why this worked in the previous SDK, but usleep() seems to work with smaller values.

1000000 must be too high and cause an overflow. Please use sleep() if you need anything larger than a second.

Best,
Kevin
