Partial Changes Migration Guide

usbh_initialize

usbh_initialize has added event_handler parameter starting from v1.6.0. Usually not needed, can pass NULL.

dwc2 glue st

Starting from v1.5.0, dwc2 glue file has built-in low-level initialization, such as usb_dc_low_level_init, which depends on HAL_PCD_MspInit and HAL_HCD_MspInit. Must use stm32cubemx generation. Third-party platforms do not guarantee having these function implementations, check by yourself.

dwc2 glue

Starting from v1.5.1, dwc2 adds struct dwc2_user_params for implementing different configurations for multiple dwc2 ports. It replaces usbd_get_dwc2_gccfg_conf and usbh_get_dwc2_hccfg_conf functions, and adds dwc2_get_user_params function implementation, example as follows:

#ifndef CONFIG_USB_DWC2_CUSTOM_PARAM
void dwc2_get_user_params(uint32_t reg_base, struct dwc2_user_params *params)
{
    memcpy(params, &param_common, sizeof(struct dwc2_user_params));
#ifdef CONFIG_USB_DWC2_CUSTOM_FIFO
    struct usb_dwc2_user_fifo_config s_dwc2_fifo_config;

    dwc2_get_user_fifo_config(reg_base, &s_dwc2_fifo_config);

    params->device_rx_fifo_size = s_dwc2_fifo_config.device_rx_fifo_size;
    for (uint8_t i = 0; i < MAX_EPS_CHANNELS; i++) {
        params->device_tx_fifo_size[i] = s_dwc2_fifo_config.device_tx_fifo_size[i];
    }
#endif
}
#endif

host serial

Starting from v1.6.0, host adds host serial framework for unifying all serial-like devices. The following APIs need to be replaced with new serial APIs:

int usbh_xxx_set_line_coding(struct usbh_xxx *xxx_class, struct cdc_line_coding *line_coding);
int usbh_xxx_get_line_coding(struct usbh_xxx *xxx_class, struct cdc_line_coding *line_coding);
int usbh_xxx_set_line_state(struct usbh_xxx *xxx_class, bool dtr, bool rts);

int usbh_xxx_bulk_in_transfer(struct usbh_xxx *xxx_class, uint8_t *buffer, uint32_t buflen, uint32_t timeout);
int usbh_xxx_bulk_out_transfer(struct usbh_xxx *xxx_class, uint8_t *buffer, uint32_t buflen, uint32_t timeout);

Replace with:

struct usbh_serial *usbh_serial_open(const char *devname, uint32_t open_flags);
int usbh_serial_close(struct usbh_serial *serial);
int usbh_serial_control(struct usbh_serial *serial, int cmd, void *arg);
int usbh_serial_write(struct usbh_serial *serial, const void *buffer, uint32_t buflen);
int usbh_serial_read(struct usbh_serial *serial, void *buffer, uint32_t buflen);
