Windows 7 BOOTP/DHCP/TFTP server program needed

Note: This was originally posted on 23rd December 2012 at http://forums.arm.com

Dear ARM folks:

I am trying to boot a Texas Instruments AM335x evaluation board using the Windows 7 USB RNDIS driver.
AM335x is a ARM Cortex-A8 microprocessor. In ROM code it supports booting using common protocols:
On USB: RNDIS + TFTP, On Ethernet: TFTP and on UART Xmodem + Kermit.

We need to be able to perform flash recovery operations on both Windows 7 and Ubuntu Linux.

On a Ubuntu Linux 10.04 LTS host, dhcpd is capable of selecting the image file based on the received BOOTP message.
So it serves a sequence of image files: u-boot-spl.bin, then u-boot.img and finally uImage.
The dhcpd.conf file contains the following code:

if substring (option vendor-class-identifier, 0, 10) = "AM335x ROM"
{
     filename "u-boot-spl.bin";
}
elsif substring (option vendor-class-identifier, 0, 17) = "AM335x U-Boot SPL"
{
    filename "u-boot.img";
}
else
{
    filename "uImage";
}

Thus, the dhcpd BOOTP server on Linux is capable of automating the three-stage boot process.

On Windows 7 we have used tftpd32.exe, but that program is only capable of serving one
image file for tftp transfer. See attached procedure. Since many ARM processors are capable
of Ethernet or USB RNDIS booting, there must be a server program for Windows 7 that has the
required functionality.

Do you know of a DHCP/BOOTP/TFTP server program for Windows 7 that is capable of using the
vendor-class-identifier (DHCP option 60) to select the bootfile filename (DHCP option 67)?

Thank-you for your consideration,

Michael Tadyshak
