I am write the bin file in my flash using own bootloader(eg: usb host msc class firmware upgrade) it's working properly without any problem.Same thing i did using hex file it is not working what i do?

Using ADC in interrupt mode, using callback HAL_ADC_ConvCpltCallback() to read values from two channels. But I am getting OVR error.

I place a break point in the callback HAL_ADC_ConvCpltCallback() and the first time it is entered EOC, EOS, OVR are all set. So I have already missed reading a conversion. How are mulitple values read using interrupts. After reading through the doc...

How to integrate uIP stack on stm32?

Hi,I am working on stm32 device which is interfaced to LAN9250 using SPI.i want to integrate the stack(i am not considering the lwIP due to very less RAM available on MC.)Has anyone ported uIP stack on stm devices? i want to send UDP packets from MC ...

I am using stm32f746g discovery board. I am tried "usb host msc class firmware update" I segregate my internal flash, 0x08000000 to 0x0804000 - USB boot application 0x08040000 to 0x0810000 - USER application

Prior to this i am trying to jump the user application from boot application, but it is not working. After change the linker file script in my user application it's working properly.My application run at 0x0804000.Now my problem is everything i am do...

I have an application which is running properly at the starting location i.e 0x0800 0000 (after usb boot) . If I change the starting location to 0x0800 4000 the application is still running this location 0x0800 0000 how to change flash address?
