Hello,
I have been having trouble with the Tiva EMAC DHCP. I have posted a couple of forum requests but none seem to really fix the problem. Here is were I am at right now. When I use Code Composer to flash the 1294XL card and start the code I get a DHCP address less than 50% of the time. I used wireshark to monitor the DHCP activity. When I get a good DHCP address I see a correct protocol exchange between the 1294 board and my network DHCP server. When I fail to get a DHCP address I see no DHCP packets from my 1294 board.
When I run ROV EMAC and get a good DHCP address I see the following,
rxCount = 87
rxDropped = 0
txSent = 4
txDropped = 0
When I don't get a DHCP address I see,
rxCount = 0
rxDropped = 0
txSent = 3
txDropped = 0
Another interesting item. When I disconnect code composer and manually reset the card it gets a good DHCP address 100% of the time. The same when the card is repower -- it gets a good DHCP address 100% of the time.
I have loaded the latest TI-RTOS but still are having problems. Here are my TI-RTOS release numbers,
TI-RTOS 2_01_00_03
TivaWare_C_Series-2.1.0.12573c
bios_6_40_03_39
ndk_2_23_01_01
Uia_2_00_01_34
Anyone seen this before? I have been struggling with this since June and need to get it fixed soon!
FYI...I had a TI software engineer recommend that I load the latest TI-RTOS the other day. It looked like it fixed the problem but in the end it did not. I just happened to get a bunch of successful DHCP trys. Now this morning I am getting almost no successful DHCP address trys.
Best Regards,
