STM32F767ZI could not remapped to internal SRAM

Hi folks, I have tried to run my complete program out of internal SRAM to speed up the IRQsbut if I come to svc 0 it failsprvPortStartFirstTask: 20005ee0: ldr r0, [pc, #32] ; (0x20005f04) 20005ee2: ldr r0, [r0, #0] 20005ee4: ldr r...

STM32F765IIK6 Reflow Problems

We are using STM32F765IIK6 176 pin 10x10 0.6mm UFBGA, die rev "Z". Whilst processing these through SMT solder reflow (using an 8 zone forced air convection oven) we had a number of these devices failing, due to the substrate of the BGA package dishin...

production ready STM32 boards

Hi,Does anyone know if there are any companies out there that sell production ready stm32 hardware boards. I appreciated there would be a lot of variations regarding io etc.. but i just wondered if it was a "thing" or if the only board are typically ...

I am working on STM32H743 micro operating as a slave I2C device. I am able to write to the slave device by a master I2C device but I can't seem to read.

I have done some investigation and arrived that the problem is with the "DIR" bit in the Interrupt Status register not firing to indicate whether to do a Read.uint32_t isr_trace[64]; int isr_count = 0;   void I2C2_EV_IRQHandler(void) { isr_trace[...

[How to] From Mechanical to Capacitive controls Guide (Buttons with sharp edges and 2mm clearance, 2 layer pcb with cover glass (50x70mm))

Even though most of you may be relatively familiar with the various types of mechanical controls, the same does not necessarily apply for capacitive ones. So, let’s start off by defining the most basic elements of capacitive sensing.Capacitive button...

Hi I am working on the ADC peripheral of STm2 f401re board, I am unable to obtain a good signal for greater than 10khz. Can you please help me with the same

F4 DMA2 errata - how to handle that

Hello!We have choosen the STM32F407/427 for our product, a couple of years ago.It fits with the speed, and also with the possibility to use DMA for mutliple peripherals.Now, as we have found out the hard way, the DMA2 fails while handling ADCs and SD...

Hello, I try to figure out if and how it is possible to use dual qspi with two separate flashes, one for the application (program) and one for the file system (data).
