Starterware/TDA3XEVM: GPIO toggle from SBL and Starterwave example gives different output

Part Number: TDA3XEVM

Tool/software: Starterware

Hello everyone,

I toggled GPIO3 pin 18 from Starterware gpio output example and I got perfect square wave signal. When I try to do the same from sbl (sbl_tda3x_main.c in PostIPUTESOC function) square signal is a little bit curved.

What is the difference in calling the same functions from these two places?

BR,

Jho.
