Sorry.
Link to the datasheet for anybody else here.
I didn't know because when you look at the pinout on page 16 of the datasheet you can see that Port 0 (Channel 0) is a MDI and the MAC0 (CPU Port) and MAC6 (another RGMII port) are on different pins.
There is a MDI to PCIe bridge between the...
Hi,
I am hoping that you will be able to help me with this problem.
I designed a board using the AR8327N switch IC and connected an input to Port 1 and two devices to Port 0 and Port 2.
Throughput from Port 1 and Port 2 is fine and is not a problem. The problem is with Port 0 which I didn't...
Hi,
Does anybody here use Altium's ActiveBOM feature?
I have a problem where I don't get pricing info from Farnell supplier in ActiveBOM document, but it shows up if I manually set supplier link in schematic document.
Mouser and Digikey prices all show up fine.
Does anybody know a solution to...
I have cut the NMI line and the program now starts normally. For some reason it seems to lock up if you assert it at power-up. Thanks to everyone for their help.
Don't know why they wouldn't write this in the datasheet :-? .
But now I have a different problem. The pin that has NMI also has...
JWHassler:
A programmer took a look at my program and also looked if I was uploading the software to SRAM, but quickly dismissed it because the RAM is too small. The code size is approximately 15kB and RAM size is 4kB.
ps: I don't really know how to upload the code to SRAM :P

Sorry for not replying sooner. Here are some more result.
5V power suppy 1s after power ON. Looks clean to me.
Reset signal 1s after power ON. Looks OK.
I probably can't measure clock frequency since it's an internal oscillator.
I disabled the watchdog of the driver and the problem...
I added some debug code that blinks the LED and I got the same result.
Reset signal is connected to PWRGD pin on the DRV8305 driver IC as it says in the datasheet. This however can't be the problem as the previous prototype didn't have this connection and the problem was still there.
Reset...
Hi!
I have encountered a really weird problem that I can't solve.
Problem occurs after I power cycle the microcontroller. I load the program using debug or run in S32 design studio (Eclipse) and after I power cycle the device nothing starts.
Reseting the target without power cycling works...
I increased the current limiting resistor to 200mOhms so that should give me a current limit of 1A. It's working now.
Thank you all for helping.
I know that there is no isolation. Microcontroller has a separate 5V LDO regulator. Boost switcher is there to power the mosfet driver in case of low...
The current limit/sense resistor is on the PCB and is marked as "R1". I used the excel tool that the manufacturer supplies and I simulated the circuit with a similar set-up.
The output current consumption is low (around 50mA) as this is used to power only the microprocessor and another IC, so...
VCC is the supply voltage. It ranges from 3V to 35V. Vdd_d is the output voltage. It should be around 7V when the input voltage is lower than 7V.
This boost circuit is just to supply the necessary voltage when the supply voltage is too low.
More info:
When I power up the circuit and the boost...
Sorry about that. I checked my schematics and layout and everything seems ok.
I don't understand the device selection line. If it's boost IC then it's NCV3063DR2G in SOIC-8 package.
Here is the schematic and layout:
Hi
I just got my prototype boards and I'm currently testing it, but there is a problem.
After I turn on the power supply the NCV3063 starts working. I can see the timing oscillator saw and the switching but only for approximately 1ms.
After that the oscillator stops (no more saw waveform) and...
One way to increase the speed that the motor runs at is with advancing the timing with which you excite the motor.
Try exciting the next coil just before you switch off the current one.
At that speeds you probably have to take into account the inductance of the motor. The inductance causes the...
