Some iMX6 platforms will meet "EHCI timed out on TD" when reading or writing data to USB disk. The root cause is last QTD reports data buffer error. Accroding to RM, this event indicates that an overrun of incoming data or a underrun of outgoing data has occurred for this transaction. This would generally be caused by the host controller not being able to access required data buffers in memory within necessary latency requirements.
How do you even trigger this in U-Boot ?
