Hi @rprr, It looks like attila accidentally tagged the wrong user, but you can see his report on using the RPi4 rev B above this post (link in case the post gets moved). Thanks, JColvin

Hi @andres04, I have sent you a PM about this. Thanks, JColvin

Hi @PrasadK, I have sent you a PM regarding this. Thanks, JColvin

Hello, For those reading this thread, I have sent a PM with instructions on how to reprogram the JTAG SMT2's. Thanks, JColvin

Hi @davittarius, I apologize for the delay; I have sent you a PM about this. Thanks, JColvin

Hi @kmesne, Given the two options, I'd definitely prefer using the HC-05; it is bluetooth compatible (so you could always pair it with your phone if needbe) whereas the HC-12 is a long range wireless transmitter that is not bluetooth based. Plus I do not think you will need to be able to communicate with your remote controlled vehicle from 1.8 kilometers away. To be fair, they both appear to be straightforward modules to use, so both will work, but the HC-05 will offer a little more flexibility in what all can be used with the project. Thanks, JColvin

Hi @kmesne, Let me see if I see if I can help clarify a few things. The good news is that there is not a wrong way to do your project, provided it meets all of the given requirements. However, there are certainly harder and easier ways to accomplish this project. As a general policy of the staff on the Digilent forum (which has been unofficially adopted by a number of our kind and helpful forum members that offer advice on their own free time) is that we don't actively complete homework assignments or semester projects for people because we believe that approach isn't truly helpful for anybody trying to learn (and it could be construed as cheating). I believe the folks over at reddit feel the same way based on what I saw. Naturally, this does not prevent you from looking to see if there are similar projects already existing online that you could use as a guideline for your own project, but realize there is no guarantee that what you find will work for your system; you will likely have to do a bit of work changing it to fit your requirements/needs. Based on what you have described both here and in other places, I would like to believe that there are some resources available at your institution that can help guide you in making the needed steps and design choices for your project, but you will know that answer best. On the other hand, if you have specific questions on how particular part of design might work and have done some due diligence on accomplishing this for yourself, we can likely give you some advice. Let me know if you have any questions. Thank you, JColvin

Hi @herve, Re-reading this thread I realized that I was stuck on the "add-on board" side of things, but if you are fine with a completed commercial product (such as @Notarobot mentioned) I would be remiss if I did not also mention Digilent's Analog Discovery 2. Thanks, JColvin

Hi @spesyvyi, We have reached out to another engineer about this to see what their thoughts are. Thank you, JColvin

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

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

Hi @gytisb92, I have sent you a PM about this. Thanks, JColvin

Hi @juergenR, Welcome to the Forums! 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
