Hi,
Thank you for your response.
USB works on my board, I tested it with code generated by: STM32CubeMX.
STM32CubeMX generates only one USB interface code, and it is not
possible use few USB interfaces;-/
That is why I'm trying use libopenmc3:)
I reused settings from STM32CubeMX rcc tab, and I've got, something like:
const struct rcc_clock_scale rcc_cs_96 = {
.pllm = 8,
.plln = 192,
.pllp = 2,
.pllq = 4,
.pllr = 0,
.flash_config = FLASH_ACR_DCEN | FLASH_ACR_ICEN | FLASH_ACR_LATENCY_3WS,
.hpre = RCC_CFGR_HPRE_DIV_NONE,
.ppre1 = RCC_CFGR_PPRE_DIV_4,
.ppre2 = RCC_CFGR_PPRE_DIV_2,
.power_save = 1,
.ahb_frequency = 96000000,
.apb1_frequency = 48000000,
.apb2_frequency = 96000000,
};
Main code is:
int main(void)
{
rcc_clock_setup_hse_3v3(&rcc_cs_96);
rcc_periph_clock_enable(RCC_GPIOA);
rcc_periph_clock_enable(RCC_OTGFS);
gpio_mode_setup(GPIOA, GPIO_MODE_AF, GPIO_PUPD_NONE, GPIO9 |
GPIO11 | GPIO12);
gpio_set_af(GPIOA, GPIO_AF10, GPIO9 | GPIO11 | GPIO12);
usbd_device *usbd_dev = usbd_init(
&otgfs_usb_driver, &dev, &config,
usb_strings, 3,
usbd_control_buffer, sizeof(usbd_control_buffer)
);
usbd_register_set_config_callback(usbd_dev, cdcacm_set_config);
while (1) {
usbd_poll(usbd_dev);
}
}
My input HSE crystal is 8MHz.
Still doesn't work... But also trying get to work that...
Thanks
Zygmunt
