STM32F429I-DISCO USB FW Upgrade code issue

STM32F429I-Discovery_FW_V1.0.0\Projects\FW_upgrade\src\usb_bsp.c

PE1 (SDRAM NBL1) is NOT the over current pin, OTG_FS_OC is PC4 per the schematic

#define HOST_OVRCURR_PORT GPIOE

#define HOST_OVRCURR_LINE GPIO_Pin_1

#define HOST_OVRCURR_PORT_SOURCE GPIO_PortSourceGPIOE

#define HOST_OVRCURR_PIN_SOURCE GPIO_PinSource1

#define HOST_OVRCURR_PORT_RCC RCC_APB2Periph_GPIOE

#define HOST_OVRCURR_EXTI_LINE EXTI_Line1

#define HOST_OVRCURR_IRQn EXTI1_IRQn

This is compounded elsewhere with an EXTI Interrupt Handler

STM32F429I-Discovery_FW_V1.0.0\Projects\FW_upgrade\src\stm32f4xx_it.c

Not sure any of this is used here, but it clearly came from somewhere else.

Also the USE_ACCURATE_TIME makes assumptions about the TIMCLK being 72 MHz (6 * 12), which again needs more thought in the porting.

Hi Clive1,

Thanks for all your valuable feedbacks on the STM32F429I-DISCO.

They will be taken into account as soon as possible.

Just to be precise for users fixing the issues by themselves waiting for official release: OTG_FS_OC is PC5. PC4 is the OTG_FS_PSO.

Best Regards
