Isochronous endpoint issue with USB drivers on STM32G491 we setup an isochronous endpoint and are having an issue where every other frame sends the desired data sandwiched between garbage data. For isochronous the parameter ep_kind into the fonction : HAL_PCDEx_PMAConfig(PCD_HandleTypeDef *hpcd, uint16_t ep_addr, uint16_t ep_kind, uint32_t pmaadress) must be PCD_DBL_BUF. The parameter pmaadress (EP address in The PMA) is like that: EP address in The PMA: In case of single buffer endpoint this parameter is 16-bit value providing the address in PMA allocated to endpoint. In case of double buffer endpoint this parameter is a 32-bit value providing the endpoint buffer 0 address in the LSB part of 32-bit value and endpoint buffer 1 address in the MSB part of 32-bit value.
