This ECU has pinout similar to ECU11 (mirrored). The DSI and DSO pins are different as in the picture. The erase and program is very fast. Need to make the RP# pin pull to 12V with a 150 ohm resistor. No new target XML needed. The ECU411 is working for this ECU. ... https://www.youtube.com/watch?v=qZJBc9gX21k
Mac version demo. Same as the other one http://youtu.be/Hy7XGNceuAo (Win)
This is the first DCU3 target that USB JTAG NT supports. CPU Sti5105. More DCU3 devices will be added. The program now is very simple with USB JTAG NT UI and speed is OK.
The fast programming is not implemented due to
1. It needs more memory and not available when the box is bricked.
2. The sprogram is already pretty fast.
The fast programming might be implemented in the future if required. (less info)

E38 has slave CPU. 32KB flash.
16KB start at address 4000-7FFF
another 16KB at address C000-FFFF

The key is to have lower than 3.3v power supply.
Both USB JTAG NT and u-Link NT can program the BIOS flash within a few seconds. Compared other video to desolder the flash, this method is much easier and fast.

u-link NT is replacing USB BDM NT to program MC6833X CPU.
u-link NT has the highest clock set to 9MHz instead of 6MHz. The read speed is faster then USB BDM NT.

Software 1.10.
EEPROM DS2431, 1Kohms resistor is used as pull up. The internal pull up resistor is about 30KB. The DS2431 needs 300ohm to 2.2Kohm pull up resistor. 3.3V from u-Link is used.
Read and write is simple and quick (because the size of the EEPROM is very small).

Original video is flash format. Convert to MP4 for better viewing experience. The new NT software looks different than this one but the concept is the same.

This is LG34um95 board. The SPI flash has the software protection on.
Use command w 6\w 1 2 to unlock it and do normal programming.
If nothing comes after the detect flash, then the flash does not have the software protection on. In this example 9c is the status.

I want to program TWO SB6121 modem at the same time.
Simply plug in two u-Link NT before start USB JTAG NT software (Windows version only), The UI will be different. Read back is disabled.
You can setup one modem while the PC is programming the other device.
One thing to note (different than single device mode), when unplug the u-Link NT, you need to plug back to the same USB port to continue your work. Plug in to different port than your original port (before the software starts) will not work.
Max allowed u-Link NT(USB JTAG NT) is 16. You can program 16 modems at the same time.
