TMDXBDKFP5515

Hello Titan,

BIOS mode is discussed in the FDK Windows Program User's Guide: http://www.ti.com/lit/ug/spruh46/spruh46.pdf

BIOS mode is entered by holding down the push button S1 labled 'Update' on the extension board when plugging in the USB cable into the larger J1 USB port. In the documentation the push button is called DIP switch S1, but is populated with a push button...

You can see S1 in the schematics on page 2 of TMDXBDKFP5515 Extension & Simulat.pdf: http://www.ti.com/lit/ug/sprufx3d/sprufx3d.zip

The customer probably should not ever use "BIOS mode" - it is only needed to update the software images for each of the sensors... the FDK v2 automatically determines which sensor is attached, and uses the software for that sensor...

Refer to this excerpt from the FDK Windows Program User's Guide:

"The FDK reserves four program storage spaces for different sensors. Three programs of corresponding sensor have been programmed to the FDK storage spaces: OP-100R, ATW310 and FPC1011. You can get OP-100R and ATW310 sensor from the FDK package. If you want to test the FPC1011 sensor, you can contact Tooan (www.tooan.cn).
If there are any bugs found after the release of this FDK, we will build new version program according to different sensors. You can get your FDK program updated in this mode, but you have to first connect the corresponding sensor to FDK board correctly. (The GUI will tell you the sensor type connected to the FDK core board.) In this case, the User BIOS will know which program need to be replaced in the storage space. All the new upgrade files can be get from Tooan (www.tooan.cn).
In this mode, only the “Get Version,” “Set BaudRate,” and “Download” commands will respond.
Usually, you do not need to enter this mode."

Regards,
Mark
