Webstar DPC2100 & Ambit 250 support

[david14280]

Does the USBjtagNT support the Webstar DPC2100 & Ambit 250 yet?

I didnt see it on UJModem 0.15.

dpc/epc 2100 is supported basically use the same configuration for the5100/5101 , the A250 is not supported ...yet.

cant see how the ambit 250 will ever be supported on the basis it does not have any jtag points...

Ambit 250 is supported but is there a JTAG port?

[Koevoet]

A250 is not supported yet , NT has an xml for A250 , but it was not set-up initially for a A250 , it was for a webstar epc running A250 firmware.

I think USBBDM should remove this A250 in the next release to avoid confusion.

ambit250 does not have JTAG, only 5-pin serial port. they have a noisy bootloader so that is really the only way to flash them from stock firmware to hacked (with a serial cable).

the DPC2100R1 (bcm3349) and DPC2100R2 both have 8-pin JTAG port that is different from motorola SB510x 10-pin JTAG. you need a JTAG adapter or modified ribbon cable to connect these modems to USBJTAG or PJTAG.

the DPC2100R1 w/ bcm3348 does NOT have any JTAG port, only 4-pin serial. This modem will run hacked bcm3348 firmware (sigma, sb5100mod) however the tuner in most DPC2100 is NOT supported by the hacked firmwares due to older FATSH base firmwares.

The DPC2100R1 w/ bcm3349 has a problem with it's capacitors. These modems have a VERY high failure rate from distended capacitors and most ISPs have already pulled these modems from the field. you can find them very cheap online, replace the bad capacitors for less than $1, and have a great modem that works just as well as the SB5101.

Does anyone know which ones of the capacitors in the DPC 2100 are bad. I undestand these modems have a high failure rate but once the caps are repaced they work well
