Below is the analog waveform for the SPI clock at 12MHz. How to improve the strength of this signal and get p-p 3.3V SPI clock at 12MHz ?"GPIO SPEED" set to the "VERY HIGH" setting. Apart from this, is there any additional settings required ?
Yes all that is configured correctly. Communication works fine at lower frequencies. No problems with SPI other than the strength of the clock signal at 12MHz.
