JTAG-SMT3-NC different ranges of temperatures.
Bianca replied to Alexandre_Borali's question in Add-on Boards
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 -

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

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

Hi @Dimple, Can you tell me if you used a FMC connector, which one and how were you using the board when this happened? Best regards, Bianca

Hi @Fkawall, If you have a desktop please try to use the USB ports on the back and if you have a laptop try other ports. You can also try to connect it to another computer to see if the error persists. Right now the discovery doesn't get enough power to start. Maybe a powered USB HUB could also help or to power it from a 5V external power supply. Try with what you have and see if you can see any difference on the connection. - different USB ports - different computers - shorter USB cable with data wires - Powered USB HUB - External Power supply. Let us know what you can find. Best regards, Bianca
