Gpio1moduleclkconfig jobs
...USB cable, that enables the MMU, I&D caching, enables the GPIO and sits in a loop wiggling a GPIO that is on the expansion header. This allows me to attach an oscilloscope and measure the speed. Currently a dumb GPIO wiggle takes 1.22microseconds on the 500MHz Cortex A8. my dumb code that slowly wiggles the GPIO doesn't initialise the MMU: #define OUTPUT_PIN 6 int main(void) { GPIO1ModuleClkConfig(); /* Enabling the GPIO module. */ GPIOModuleEnable(SOC_GPIO_1_REGS); /* Resetting the GPIO module. */ GPIOModuleReset(SOC_GPIO_1_REGS); /* Setting the GPIO pin as an output pin. */ GPIODirModeSet(SOC_GPIO_1_REGS, OUTPUT_PIN, GPIO_DIR_OUTPUT); for (;;) { GPIOPinWrite(SOC_GPIO_1_REGS, OUTPUT_PIN, GPIO_PIN_HIGH); G...
