TSW14J56EVM: TSW14J56EVM

Jacob,

Make sure the 5V supply connected to the TSW14J56EVM can source at least 4A. Make sure the current limit is not set to low if the supply is already rated for this.

If this does not solve the issue, please let me know the status of the LED's D1-D8.

Regards,

Jim

Jim,

Sorry for the late reply. The power supply I am currently using is a 0-30V power supply rated for 5 A. I sent my current limit to 2 A. It seems to boot up fine and all the voltage rail LEDs are powered on correctly. As for the status of LED's D1-D8 they are all off when I try to upload the firmware I want to the board.

Thanks for the response,

Jacob

Jacob,

Please set the current limit to 4A and give this a try.

Regards,

Jim

It is still giving me the same error as before. I even swapped out for other power supplies of the same model and still nothing seems to be programmed.

Jacob,

It appears this is a failing unit. If you bought this from a distributor, you will have to work with them to get a replacement. If you bought it from the TI Store, the following link has the details and a link to the form to start the return process.  Once you are on the returns and refunds page of the TI Store look for the hyperlink which says: TI store customer support form.

Jim,

I have 3 of these units and I swapped out all of them. Is it possible for all 3 to be failing units?

Thank You,

Jacob

Jacob,

Please verify jumper JP11 has a shunt between pins 1-2, JP12 has no shunt, and JP4-JP7, JP10, JP13, JP16 and JP17 have a shunt between pins 2-3. 

Please send screen shots of the GUI after the GUI first opens, then after selecting the ADC ini file, then after pressing capture. Can you also monitor the current and let me know the consumption is after each of the steps?

Are all three boards doing the same thing? When did you get these boards? 

Regards,

Jim

Jim,

All shunts are in there proper locations as specified above. The current draw remained constant throughout all steps you asked me to preform at 0.540 A. I attached the screenshots below and it is still giving me the same error. I checked with other engineers and they told me we received these boards around mid-May. All three boards are giving me the same error.

Jacob,

Do you select a ini file after clicking on "OK" in the screen shot you sent? This is required to download the firmware. Do you see the following ini files after clicking on the Select DAC green drop down arrow?

If so, what happens after you select the ini file? Please send a screen shot of that.

Regards,

Jim

Jim,

I do and after I select any of the .ini files I get that Auto Re-arm Trigger Params in DLL WRITE_REGESTER_FAILED error again. Then when I try to click the file again all it says is download firmware.

Thanks,

Jacob

Jacob,

Please send these back for a replacement per the post I sent a few days ago.

Regards,

Jim

Jacob,

Can you please send the serial numbers on the three TSW14J56EVM boards you have?

Thanks,

Jim

Jim,

The serial numbers are as follows:

T842EG3U

T843N8di

T843NDo2

Let me know if you need anything else and I will look sending these back in for replacement,

Thanks,

Jacob
