  1. Hi @Alexandre_Borali, I know it seems weird. We normally set our temperature grade for our products to be inclusive for the most sensitive component. In the specific case of this product we conducted some operational tests at higher temperature range. Upon these tests we updated the documentation with the new range for the operational temperature of the device. However, we didn't have a way to make the tests for the storage temperature, therefore we updated just what we were able to test and left the other one as per specifications of the datasheet for the most sensitive component. This is where the discrepancy comes from. Best regards, Bianca

    @kevpattkhp, Hello, I will contact you over email to sort this out. Regards, Bianca
  4. @jonoli6309, I sent you the solution in our previous opened DM. Regards, Bianca
  5. Hi Bruce, It's ok, You confirmed what I thought the issue was... There is something, and I suspect the current protection (IC13), that is defective and is putting the Dialog power supply under stress. I will send you a private message regarding the purchase details of the board, to see if it's still under warranty. If it's not. I would suggest replacing IC13 (NCP380HMUAJAATBG) and try again; if you can't find the part on stock, you can also try to bypass it. But this will leave the board exposed to short circuits and overcurrent. You can check the schematic here. Regards, Bianca
  6. Hi @Bruce_W, If the LED is blinking it means that the 3.3V power supply is not working constantly. I don't know if with a multimeter we can see the behavior, probably just with a scope, but if you have a voltmeter/multimeter, please try to measure the voltages on, C208, C176 (or C177) and C178 (or C179) while you power the board from the PC with the USB cable. It will average the values, but if the power supply is that unsteady, you might be able to see some fluctuations. There's an overcurrent protection IC on the path when using USB power. I suspect that to be the cause of the problem. Bianca
  7. Hi @ASI, Yes, please check your PMs. Regards, Bianca
  8. I will private message you for some purchase details. Bianca
  9. Hi @Samuel Quiniou, Sorry for the delayed answer. There are no board files for REV E. The only difference between rev E and rev D that might affect your design is the memory. Due to a discrepancy in the manufacturing process on these board a different DDR part was loaded on the board. This memory had the double amount of the original Rev D. We tried to collect them all and replace them with boards with the original memory because none of the available resource materials worked with them directly. We can do the same for you if your board is affected. However, if you want to use the Rev E with the bigger memory, we've put together a set of instructions on how to upgrade the projects: https://zedboardupgrade.s3.us-east-2.amazonaws.com/ZedBoard+Rev+E+project+update+procedure.pdf You'll still use the same rev D board files. If you want a corrected board, please let me know. Regards, Bianca
