hi

    how can I get high speed USB interface to host a device on STM32F4discovery?

    would i have to remove component from the kit OR just add additional PHY?

i am using USB3300 SMSC eval board. I am able to run high speed ULPI interface with STM32F4 Discovery using MSC high speed example for STM324xx boards. I get a little highspeed than fullspeed. the ULPI is running well.

1=>I can write files to USB using ULPI highspeed interface, but I can't achieve High Data rate as expected.

2=> the speed get more lower about after 1000 files written, I am using character array of length 5 , name={'0','0','0','0','0'} and after when name={'0','1','0','0','0'} the speed get lower? why is that so? is due to the long file name I am using or what else? {if i refresh the name to 0,0,0,0,0 the speed get to its original}

thanks

Hey, i got question. How you managed to fix this problem when program was continuously pooling through HOST_CTRL_XFER after failed enumeration? I've got the same problem and i can't find solution.

Also I used MSC example for STM3210C-EVAL borad.

So a bit off-topic then, perhaps a new thread with details of YOUR issue, and compiler settings, etc, might be a better route.

Hey, tech.haris can you just tell me what did you do do deal with this continuous pooling through HOST_CTRL_XFER after failed enumeration? I know it might not relate at all to my problem, but since nobody want to say something I'll be very glad to get some hint.
