AM335x Starter Kit (USB: USB0/UART0/JTAG)

Vasiliy Bogatov

Dear Support,

I've received AM335x Starter Kit (TMDSSK3358). This is reference design for my custom board.

Ok, I need some clarification about drivers to connect by USB. 

When kit is connecterd to PC (Win7) host identify this devices:

According to schematic: FTDI chip act like XDS100V2 emulator plus UART0 for MCU.

Questions:

1) Where i can download drivers for XDS100V2 and SUBARCTIC for working with Win7 Host. I want use HyperTerminal for UART0 of MCU and Keil for emulator.

2) What  is 'Subarctic'?

Thanks

    Hello Vasiliy,

    The link to the FTDI drivers are located on the Starter Kit Diagnostics page:

    http://processors.wiki.ti.com/index.php/AM335x_Starter_Kit_Diagnostics

    These probably should be posted somewhere more prominently, so we will discuss adding another link to them on the entry page.

    Hi -DK-,

    After installation drivers for FTDI from the link "CDM 2.08.14 WHQL Certified" and VCP drivers from FTDI site, host can see "USB com portXX". By the way, why newest drivers from FTDI "CDM 2.08.24 WHQL Certified" not compatible?

    But, there is still issue with "SUBARCTIC" driver. In Device Manager it is still unrecognized. What is it?

    Thanks,

    V

    And one more question:

    If I' correct, USB0 of MCU is configured by ROM code as RDNIS, right?

    How can I recognise it in Device Manager?

    Thanks,

    V

    Vasiliy,

    Yes, the ROM configures USB0 as an RNDIS device to allow for booting from USB. 'SUBARCTIC' is the friendly name for the AM335x family of devices and this Device Manager entry represents the actual USB RNDIS endpoint. 

    As for the newer version of the FTDI driver, I'm sure the newer version will also work, we just haven't tested it internally yet.

    -DK-,

    OK, here is link with inf file for RDNIS http://code.google.com/p/beagleboard/downloads/detail?name=linux.inf  what VID/PID i should write there for proper installation?

    Thanks,

    V

    Ok, to setup standard RNDIS driver just put this VID/PID: 

    USB\VID_0451&PID_6141

    This issue closed.

    I have the last question:

    I want use as reference this part of development kit (i mean one USB for MCUs USB0/UART0/JTAG) for my custom board. Is it possible? If I'm correct for this purpose i need properly configure FTDI chip. Is this configuration available for download?

    Thanks,

    Vasiliy

    For Win7, just use the built in RNDIS driver. Please see attached.

    Hello,

    Before doing the change, the SUBARCTIC peripheral connect and disconnect every 10 sec.

    When the SUBARCTIC disconnect, my serial port write CCCCCCC, then it connects back, and I stop receiving anything.

    I'm on W7, I've made the NDIS change with the  SUBARCTIC peripheral but my serial port still doesn't work:

    - I boot on a SD card with a MLO and a bootrom

    - I link my laptop and the SSK by the microUSB

    - I setup my realterm to a serial connection

    I only receive CCCC when I reset the board (the time that the SUBARCTIC reconnect)

    I've tried this on 2 computers, and on Linux. Linux detect the SUBARCTIC has a Texas Instrument Network.

    I don't get it...

    The CCCC on the serial port looks like it's ready for a UART boot.
