Hi @Dimple, I have sent you a PM about this. Thanks, JColvin

Hi @Dimple, I apologize for the delay in responding. Do any of the IC's feel hot when you have the external power supply connected or previously when you were able to measure the voltages? And as some clarification questions, what do you mean when you say you are not able to measure any voltage now? Do you mean that you weren't able to measure voltages at that particular moment, or did they all read as 0V? Is this the case for the all the locations I asked about or just the ones you listed? Which zedboard do these voltages apply to, the stand alone board or the one with the extra FMC connector? Additionally as a confirmation, has the standalone board ever been used with the custom FMC connector? Could you provide a link to what power supply you are using for the boards and have you happened to try using a different power supply (to help rule out the possibility that the power supply decided to stop working)? And as one more clarification question (sorry for having so many), when you say you are not able to program it, does that mean you are not able to detect it in Xilinx's Vivado/ISE or do you get some sort of error? Are you able to see the Zedboard in Digilent's Adept software? Thank you, JColvin

Hi @Dimple, I have a few more questions and some things that I would like you to test so that I can I have a better understanding of the situation. What type of power supply (i.e. voltage and current) are you using to power the board? Have you tried fully moving the power supply switch on and off a few times to ensure the board is fully "switched on"? I know that switches can sometimes be finicky in this way. When you say the LEDs are partially lit, are you referring to LED 13 (the power LED)? Could you measure the voltages across the following capacitors? The following are all present around IC27, located in the southwest region of the backside of the board C329 (should be 5V) C334 (should be 3.3V) C339 when J18 is set to 1.8V (should be 1.8V and I'm pretty sure you measured this already, but I'll feel better if you measure it again) C339 when J18 is set to 2.5V (should be 2.5V) The following are present around IC30, located on the top side of the board beneath the audio input/outputs C362 (should be 5V) C366 (should be 1.8V) C369 (should be 5V) The following are present around IC34, located on the backside of the board in the northeast region C388 (should be 12V) C394 (should be 5V) Thanks, JColvin

Hi @Dimple, What leads you to believe that the problem occurred while the Zedboard was being used in a standalone mode? The 1.8V is not readily physically accessible except through the FMC port, hence Bianca's question on if you used it since it is present on VADJ (controlled by J18 on the Zedboard). Can you provide additional details about the custom board you mentioned? Thanks, JColvin

Hi @Sarah, I heard back from one of our engineers and they said that a custom application would need to developed and unfortunately we do not have the time to develop it. Thank you, JColvin

Hi @rwheadon, I have sent you a PM about the RMA process. Thank you, JColvin

Hello @BYTEMAN, Taking a look at this thread, you may need to re-generate your BSP sources, or potentially delete it and create a new one. I would also make sure that all of the SDK settings (I'm not certain if you have changed any) are on their default settings. Thanks, JColvin
-
Hi @BYTEMAN, I'm not certain on the differences between the two interrupt controllers, you will likely need to contact Xilinx to see if they have any additional thoughts or concerns on this. As for the SDK debugging behavior, according to this Xilinx site, the GDB mode is depreciated, so you will likely want to instead use the "Launch on Hardware (System Debugger)" option instead for some better results, as this Xilinx forum thread seems to indicate as well. Thanks, JColvin

Hi @david bowie, I sent you a PM with the application. Thanks, JColvin

Hi @david bowie, I'll have to reach out to some other engineers to see if I can get the correct reprogramming application; the current one that I have does not have direct support for the JTAG-SMT3-NC. Thank you, JColvin

Hi @kraiskil, You can take out the screws and remove the frame without voiding the warranty (though I guess if you physically break the case that'll be a different story ). What are you experiencing specifically with the AD2? Is it detected by the WaveForms software? What do you see in the device manager (if you are using a Windows based device) when you connect/disconnect the AD2 from your computer? Thank you, JColvin

Physical connection of the XADC rig to the Nexys Video using a Pmod TPH2 (a passthrough Pmod) and a Pmod DIP (to connect the 2x6 connector to straddle a breadboard). -
From the album: Forum photos
Orange wires on the left of the Pmod are grounded pins. Wires right of the Pmod are the analog inputs (or a ground wire) for the positive inputs to the XADC on the Nexys Video -
Agreed. Digilent also sells some JTAG SMT modules that accomplish a similar task as well.
