Hello,
I'm trying to get USBX CDC Virtual COM Device configured on an STM32U535CET6. I have downloaded and tried to play matchup with the projects out on GitHub for the U5 series but have had no success. I'm currently stuck on:
/* Now check for invalid queue ID. */
else if (queue_ptr -> tx_queue_id != TX_QUEUE_ID)
{
/* Queue pointer is invalid, return appropriate error code. */
status = TX_QUEUE_ERROR;
}
queue_ptr -> tx_queue_id is empty but I can't find where it's supposed to be initialized. The project is barebones, I'm just trying to get CDC to work so I can write out to a terminal like Putty.
I have also gone through the H7 tutorial with no luck. It has to be something I missed but can't find it.
Going through the steps for the H7 that I found on YouTube, the U5 doesn't seem to have these methods:
HAL_PCDEx_SetRxFiFo(&hpcd_USB_DRD_FS, 0x80);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_DRD_FS, 0, USBD_MAX_EP0_SIZE / 4);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_DRD_FS, 1, USBD_CDCACM_EPIN_FS_MPS / 4);
HAL_PCDEx_SetTxFiFo(&hpcd_USB_DRD_FS, 2, USBD_CDCACM_EPINCMD_FS_MPS / 4);
The only method available is:
HAL_PCDEx_PMAConfig(&hpcd_USB_DRD_FS, ....)
I have a legacy file, stm32_hal_legacy.h that contains:
#define HAL_PCD_SetTxFiFo HAL_PCDEx_SetTxFiFo
#define HAL_PCD_SetRxFiFo HAL_PCDEx_SetRxFiFo
Any help would be greatly appreciated. I attached the entire project.
Kindest regards.
