Project m cobalt legacy training mode crash manual#
The configuration is got from reference manual of these 2 processors, due to no suitable board, this configuration is not validated on board. But if customer wants to use USBx_ID, for i.MX8MQ, she canĬonfigure USB_CTL0_ADDR register.Īnd for I.MX8M Mini, USBNC_n_CTRL2 register. USBx_ID is called USB PHY ID, which can also perform the same function as USBx OTG ID. During the work process, the software changes the role between device and host according to the level of the ID pin from high to low or from low to high.

USBx OTG ID is also called GPIO ID, which is the same as that of i.MX6Q. As long as the customer refers to the design method on the I.MX8M Mini-EVK, the input voltage of these 2 pins can be guaranteed Inside. There are internal voltage-dividing resistors on the USB1_VBUS and USB2_VBUS pins. In fact, customers do not need to worry about this problem. From the drawings, the external input voltage exceeds this range. Therefore, some customers have questioned the USB1_VBUS on the I.MX8M Mini-EVK. About USB1_VBUS & USB2_VBUS of i.MX8M MiniĪccording to i.MX8M Mini datasheet, USB1_VBUS & USB2_VBUS allows 0~3.9V input. USB2 is configured as fixed Host mode, USB2 OTG ID is used for detection USB1 is configured as Dual Role Mode, USB1 OTG ID is used for detection At the same time, change the connector to MicroUSB and In both development boards, the USB TYPE-C design scheme is used. I.MX8MQ supports USB3.0 and is compatible with USB2.0, i.MX8M Mini only supports USB2.0,

The i.MX Expert software team gave suggestions on software adjustments. Summarizes the answers to previous customer responses and draws two USB2.0 design schematics.Īt the same time, the i.MX expert hardware team member helped review these two drawings, and In order for customers with similar needs to complete the design smoothly, this document USB2.0 interface design similar to i.MX6Q. Therefore, these applications need to use a conventional Since the release of i.MX8MQ and i.MX8M Mini, some customers have submitted questionsĪbout the design of USB2.0 for these two processors: due to the needs of the project, there is no
