I have ported (if I may say so) the usbHost example to STM32F407VE controller but I have some questions. 1. I don't understand where is setting RCC in your example Trial_STM32F746_DISCO_USBH_HID_SES? I was forced to add SystemClock_Config(); at begin of main.c from like Keil example. After this changes my project with STM32F407VET6 start to run GOOD. Thank all!

I will upload fully project with LPC 1768 on Embedded Studio to github.com if you don't mind? github.com/PavelDorofeev/USB-D…68-Segger-Embedded-Studio

Thank you very much Martin! That is OK! My USB-HID project is working fine in Debug mode too!

Thank Martin! static OS_STACKPTR int Stack0[768]; I change the 768 value to my controller max 6xxx (LPC1768) but it doesn't resolve my problem. Well, I will teach embOS carefully....

I 'v tried to compile the USB_HID_Keyboard.c example from ...SEGGER\SEGGER Embedded Studio\v3\packages\ESPRO\USBD\Application and Release Version is working good (symbols is sended normal to PC to Text Editor), but in Debug version its does not send to PC. In Debug Mode by JLink debugger the controller stop here: Source Code (6 lines) As I have understood the controller run to OS_Error(OS_STATUS ErrCode) with OS_ERR_SYS_STACK and hang here : Source Code (10 lines)I suppose "OS_LIBMODE_DP" needs …

Yes - the problem was resolved during 3 days! Bus RESET should not occur in unattached state! - This is important message that i get on any examples permanently with my LPC1768 board. This board is from old receipt printer. This is not evaluation board. And USB D+ must be pull-up to 3.3V by 1.5K resistor. This is assigned to Host that the Device have FULL Speed Rate. I.E. this was not software problem - this was the hardware mistake. Thank all!

Thank all! I write you when it resolved.

When I connect USB cabel I step here Source Code (8 lines)I suppose that maybe: 1. I have downloaded at first emPower example with MK66 (HS USB) and changed it to LPC1768(FS USB). 2. I am disturbed about USB frequency settings. Do you recommend me some example for like LPC1768 controller with emOS and emUSB-Device? I searched it at forum and downloaded area but I not found anything.

Hi Michael! Thank you for your answer. I have launched next project with emOS normal. But I meet a problem with emUSB (on LPC1768) . I have spend two days with situation below: Source Code (5 lines)When I turn on controller after USB-Start() USBD_GetState() returned 0x10 (=USB_STAT_ATTACHED) After 2-3 seconds USBD_GetState() returned 0x11 (=USB_STAT_ATTACHED&USB_STAT_SUSPENDED) When I connected USB cabel the USBD_GetState() returned also 0x11. This occured with examples : USB_HID_Keyboard.c , US…

Hi, I am beginner. I`v downloaded SES 4.12. I have a trial licence. I`v compiled "SeggerEval_emPower_emUSBD_Audio_SES_180424" example good. This is Cortex-M4 controller. But I create new project with LPC1768 (Cortex-M3). I`v tried to compile for LPC1768 controller and I have received any errors : undefined reference to `OS_InitKern_STD' undefined reference to `OS_InitHW' undefined reference to `OS_CreateTask_DP' ... As I understood the difference in #define OS_CPU_HAS_VFP - (Floating Point) Can …
