Hi everyone,
At this time we have a problem with jorjinbsp, that need your good help.
I have used source code here: http://59.124.231.13/index.php/JAJ_2.5-P2_AP_Module_OMAP4_Jelly_Bean_Release_Notes
I want to porting chip ethernet Lan9514 to BSP TVBox, I haved referred PandaBoard’s schematics and source code to config mux pin for Lan9514. Now I can connect to Internet throught Lan9514, but I met a problem, that is:
When I just read news or listen to music, TVBox work good, but when I streaming video, system hang, at the windows console, I saw below error run continually:

I was look at and saw that this issue occured when turbo_mode is set to “true” in /drivers/net/usb/smsc95xx.c, when I set it into “false” this issue is no longer, but connect to internet is very slow. And in PandaBoard, it is “true”, I aslo want it to ensure internet speed when streaming video.
I see that, the different when set turbo_mode from “true” into “false” is that: change receiver buffer from 16k to 2048byte.
Another solution I was saw, is that, increase dalvik’s mem,
PandaBoard used file: mydroid/frameworks/native/build/tablet-7in-hdpi-1024-dalvik-heap.mk with config mem:
PRODUCT_PROPERTY_OVERRIDES += \
dalvik.vm.heapstartsize=8m \
dalvik.vm.heapgrowthlimit=64m \
dalvik.vm.heapsize=384m \
dalvik.vm.heaptargetutilization=0.75 \
dalvik.vm.heapminfree=512k \
dalvik.vm.heapmaxfree=8m
BSP TVBox used file: mydroid/frameworks/native/build/tablet-dalvik-heap.mk with config mem:
PRODUCT_PROPERTY_OVERRIDES += \
dalvik.vm.heapstartsize=5m \
dalvik.vm.heapgrowthlimit=48m \
dalvik.vm.heapsize=256m \
dalvik.vm.heaptargetutilization=0.75 \
dalvik.vm.heapminfree=512k \
dalvik.vm.heapmaxfree=2m
I was try to change, but no effect,
I want to ask you:
BSP TVBox is suported to porting chip Ethernet Lan9514, don’t you?
If yes, I do that is ok?
You have saw that issue? How to solve it?
Everyone, please help me solve this issue,
Thanks you very much!
Best Regard,
