Figure 15: PMA-005 USB-Host Interface
With the phyCORE-i.MX Carrier Board PCB versions 1280.0, 1280.1 and 1280.2 there is no
possibility to use the onboard USB-Host interface with the phyCORE-i.MX35 module. That’s why
Phytec decided to put a separate USB-Host interface on the i.MX35 mapper board. This USB-Host
interface is populated when the pyhCore-i.MX35 module should be used with phyCore-i.MX Carrier
Board version before 1280.3.
After a workaround with PCB version 1280.3 it is possible that the phyCORE-i.MX35 module uses the
USB-Host interface of the phyCORE-i.MX Carrier Board. This functionality is given with PCB
version 1280.3 or higher.
