Hi everyone!

I'm new to the STM32 world, so I'm looking for some concrete example that USB OTG application with a STM32 uC.Did someone have sucess with a similar project that can be shared here?If however you can advise me to guide me, I would be thankful.

I have got the ZIP file you cited - (it's

)I used LeJOS language to communicate the Lego NXT to the PC;There were two programs: A java applications running on the NXT and another Java app running in the PC;I have ran two programs:   1º - Download data into the NXT flash memory;   2º - Data exchange between NXT and PC;The results are in this

. (Google Drive)The NXT uses Fantom Driver for USB comm. Can I modify the STM32 MSD driver taking base on the Fantom? Could it be useful? (however, I still have no technical info about it)Thank you very much, Tsuneo!

Inside the NXTGCCECLIPSE-project files I found the file

d_usb.c

. This file contains several USB device info; Tsuneo, could you see this file? I think it can be useful. It's attached. Thank you. ________________ Attachments : d_usb.c : https://st--c.eu10.content.force.com/sfc/dist/version/download/?oid=00Db0000000YtG6&ids=0680X000006I0b0&d=%2Fa%2F0X0000000baz%2FhPRbZ4fXsibu2DL4SXSfFS72sJZD1r5ohYgD0R__nxc&asPdf=false

- looking for some help]

• Recently I have modified the MSC library to accept my device as a MSC device; So the STMF4 did the complete enumeration;
• Second what I watched on a USB sniffer, after the device is ready, just Bulk transfers are performed; Tsuneo recommended this analisys, at[DEAD LINK /public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/USB OTG for custom an USB device&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580009C4E14902C3CDE46A77F0FFD06506F5B&TopicsView=https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/AllItems.aspx?Paged%3DTRUE%26p_StickyPost%3D%26p_DiscussionLastUpdated%3D20120628%252003%253a22%253a38%26p_ID%3D23204%26View%3D%257bF47A9ED8%252dE726%252d42BE%252dACED%252d732F13B66581%257d%26FolderCTID%3D0x012001%26PageFirstRow%3D41&currentviews=212]this post;
• The device has two endpoint bulk - like MSC devices;

• Using BulkSendData I get a packet in the device side - I think it worked fine;

• Using BulkReceiveData it doesn't work - However I have no ideia why the error occours. When I stop the degug, the program stop on interrupts routines, at the usb_hcd_int.c file. Is the host expecting something from the device? Can't the device response the host? I'm investigating about this currently.

If someone has some idea, please help me.

stm32_nxt, were you ever able to get anywhere with this issue of yours? I am also working on a similar usb otg issue as you are. I am trying to communicate to a device via USB using a Bulk interface also.

Hi i wanted to ask you if you have an idea about the porting netmf : i want to change the Oberon micro-system drivers(like usb, spi and i2c) from direct register access to hal layer to make it more portable but when i try to open the Oberon Library it is open with Block note, so i can find the declaration and the reference of many functions 

can you please help me to know how to open Oberon project with Keil 

and how can i migrate to the hal layer

Best regards,

Rihab.
