AM2634-Q1: USB Host mode support on AM2634

Part Number: AM2634-Q1
Other Parts Discussed in Thread: AM2634, SYSCONFIG

Tool/software:

Hi
We are planning to use AM2634 microcontroller in our product and we have a requirement to interface pendrive  to support copying files from EMMC  and vice versa. We are planning to use a UART-USB (type A) converter module over UART4 of AM2634.  On the software part I am unable find any example code / support regarding USB host driver on AM2634. Also USB is not available in syscfg tool for AM2634. Kindly let me know if the above requirement is possible with AM2634 and if supported please share any reference documentation to start with 

Thanks in advance

    Hello Nishanthkumar,

    AM2634 does not have a USB peripheral and therefore it wouldn't have any USB host drivers in SysConfig. The TI EVMs use a UART-to-USB emulation bridge through the XDS110 circuit to handle USB comms with PCs for evaluation but this is standalone from the AM2634 MCU.

    If you are using a UART to USB bridge on UART4 the same concept should apply and your USB drivers and enumeration would come from that bridge IC, not the AM2634 which would only be configured for UART operation.

    Best Regards,

    Hi Ralph,
    Thanks for your quick response and support

    Yes, we are planning to use a UART to USB FTDI chip that support USB host mode...We can close this issue
