Other Parts Discussed in Thread: TMDS570LS31HDK

Hi,

i connected the HDK board and gave the power supply and flashing some programs but it is not flashing and giving some target power loss error need to connect the usb emulator or turn on the power supply .i connected the powersupply and USB emulator also but it is not flashing wat's the problem

Can anyone help me (note:the ds2 & ds4 led is not glowing).

I checked the fuse F1(on top of it,it is written 150 F,24V), It is fine.

I checked the TP12 --> i'm getting 5V.

For TP14(1.2V) and TP16(3.3V) --> i'm getting 0V and 0.1V respectively.

I checked the right end of F1, it is giving me 12V.

Thanks,

Harsha

Harsha,

Actually, the 'large' part that has F1 on top of it (assuming 'up' is in the direction of the power jack) is the Ferrite bead.

The fuse is a much smaller part to the left of the text F1. It's probably blown. Easy to blow if you accidentally short one of the connector supply pins to GND say if probing w. a scope or some other tool that has a ground lead.

I think the IC's which give the 1.2V and 3.3V is not working.

can anyone let me know the part number of those IC's.

On the board,it is labelled as U30 and U35.

Harsha,

If you follow the link below, it will take you to the product page for the HDK. There you will find a user guide for the HDK and a downloadable zip file containing all the design information for the HDK (gerber files, schematics, footprints, etc.)
