Hi, I have made a data logger system with RL-TCP, and every thing works great, but if I do not make any connection with my board, after 24 hour, the Ethernet link would be put in sleep,both Ethernet LED's would be turn off, and when I try to connect to the device using a browser, I can not reach it, the only way to get to it is to reset my board manually, So do you have any Idea what's going on? why the Ethernet goes into sleep? Regards
You haven't given many clues to what you've really got.
I have a system using RL-TCP and I don't see any such issue.
Hi, I'm using LPC1768 as MCU, RTX and RL_TCP and Flashfs as components, I have build a dynamic web page that shows IO status of LPC, everything works as intended when you see the board html pages, but If you do not use your browser to see any page after 24hour the RJ45 connector LED's would be turned off,normally they are on and blinking (green on and yellow blinks if there is some activity),But both of them are off after 24 hour if you do not invoke any webpages form LPC,
I hope this would help, Because my project is very big and complex,if you need something specific,please tell I will show that part of code in here Regards
I suggest you look at the Ethernet driver for your board.
I have used the DP83848 driver that ships with Keil,there is only one Power Control function in it that I have commented out the power off case, But I still got the same results
//case ARM_POWER_OFF: // reg_bmcr |= BMCR_POWER_DOWN; //break;
