Hello,
I am using DE1-SoC to start bare-metal programming for dual-core Cortex-A9 ARM hard processor, Cyclone V. My code is just Toggling a GPIO pin to measure maximum toggling frequency for hps using Altera HWLIB as bellow while (true) { alt_replbits_word(GPIO_addr , 8388608, 8388608); alt_replbits_word(GPIO_addr , 8388608, 0); } I get 500KHz as maximum GPIO pin toggling frequency. My questions are: 1- Is this the maximum GPIO toggling frequency or I can increase it to reach more than 10MHz, if yes how can I ? 2- As I am working with 925MHz Processor It is supposed to get higher toggling frequency, is that true? Regards,Link Copied
