STR71x virtual com port sample code OK?
2007-11-28 12:55 PM
I run the virtual com port sample code of STR7/9 USB developer kit,
it is OK with STR75 sample code in STR75 board , but for STR71 sample code in STR71 board, still unkown USB device! Is the sample code of virtual com port for STR71 OK?2008-01-14 05:06 AM
Check the system clock configuration for STR71x board (hw_config.c file ), maybe another oscillator value is used on your board? the example is based on 16MHz oscillator on the STR710 eval board :D

I have not managed to run the STM virtual com port example when compiled with gcc/winarm, but could do it with evaluation keil.
I have inlined Set_system(), Set_USBClock() [this one was empty], USB_Interrupts_Config() and changed: // Set_system() RCCU_MCLKConfig(RCCU_DEFAULT); RCCU_PCLK1Config(RCCU_DEFAULT); RCCU_PCLK2Config(RCCU_DEFAULT); RCCU_PLL1Config(RCCU_PLL1_Mul_12, RCCU_Div_1); // 4 MHz quartz on board // Set_USBClock() PCU->PLL2CR = 0x0590; // 48 is 4 *12 /1 ARM7TDMI, ARM7TDMIFR2T6, STR711, STR-H711 (Olimex board) [ This message was edited by: mlg7 on 13-04-2009 11:28 ] [ This message was edited by: mlg7 on 13-04-2009 11:32 ]
