RE: use easyweb with Ks8721

However, some boards doesn’t work even ks821 I connect these pins together: In case of any difficulties this may be an important tip. I wondered why that k8721 so I wonder whether the trick was to connect pads 22 and 9 underneath the chip and remove pin 22? I don’t understand why we need to connect these 2 pins together, the datasheet provides no explanation. This pin have to connect 9 number of KS The following requirements were not part of the basic hardware test: Looking the code I set my lan with IP: Only for single port devices, because only one PHY address can be used.

If my implementation works, I will keep you updated!

Ok, I finally found something: The first three requirements are assumed to be fulfilled either according to the data ls8721 or vendor notice. On mine, there is a small wire below the chip that I found out when I soldered the chip out. I’ve received no reply from Olimex unfortunately.

An analysis of B cell Enhanced Link Detection is generally recommended because additional faults are detected and link loss reaction time is improved. Internal pull-up at MDC. The phase relation has to datashewt the same each time the PHYs are powered on.

If I remove it, I reveive no packet at all. If TXER is asserted for one or more clock periods, and TXEN is asserted, the PHY will emit one or more symbols that are not part of the valid data delimiter set somewhere in the frame being transmitted. There is a SAM7X running on-line at: But I don’t see any connection to pin 9. This needs to be corrected as we believe this is the cause of the receive errors misalignment.

Post ethernet phy on sam7x The misalignement can be explained by this. Offenders will be held liable for the payment of damages. No registered users and 1 guest. Ah ah, it is interesting! The SAM7X has to be carefully controlled during chip startup since its internal pullups cause a bit of a difficulty when the PHY configures itself over the hardware settings read at reset.

The best way would be to check with a simple multimeter when I removed the part, I didn’t know where to search. Who is online Users browsing this forum: Hardware tests are typically performed with only one of the ESC types, e.


But This problem is not from software. This means the board and the schematics are differents.

PDF The uTasker is free for educatational and other non-commercial work – send simple application if interested in using or evaluating – found here: The phase offset is compensated inside the ESC either manually by configuration or automatic: Devices with one or more EBUS ports which do not support port-wise configuration can not be configured to use Enhanced link detection. The Auto TX Shift feature compensates these phase shift variations, as long as the phase shift is at least constant while the link is up.

Receive and transmit delays should be deterministic. From the software point of view the PHYs are basically IEEE compatible and so basic functions all work the same and the programming uses the same registers. Hi Mark, I wondered if you have few minutes to check if theses 2 pins are not connected together on your Olimex board.

PHY address offset must be 0? Does it work with 10MBit mode at Olimex kit? Power consumption should be as low as possible.
