Hello,
I'm using LCP1788 with a ethernet PHY.
The problem is that some times it receives from PHY a ethernet frame with most part of it filled with 0x55.
I'm using wireshark for comparing between transmited and received frame. And most part of the time the received frame is equal to the transmited from PC but sometimes the LPC1788 receives a frame filled with 0x55.
Does anyone have a clue about this?
Thank you.
Henrique
Hi, I meet the same question ,the LPC1788 send the package full filled with 0x55,did you get the solution,please tell me ,thank you very much!
i had the same problem then fitten more ram. cool fix.
I just added more RAM and disabling all interrupts by using __set_PRIMASK(1) and __set_PRIMASK(0) for enabling.
And actually now I'm using external SDRAM for ethernet instead of internal RAM.
After that I have never gotten the problem again.
Best regards
