Sorry this is a report, I tried to post yesterday, but cannot find it today.Trying to use the bootloader via USB, and this works on the Nucleo PCB, but not on our prototype. We have no crystal as we expected that the clock recovery would work in boot...
We wish to bootload a STM32H503RB using USB. This works on the NUCLEO-H503RB, but after resetting the processor on our PCB with BOOT0 high windows reports "Device Descriptor Request failed".AN2606 states that CRS is enabled for the DFU to allow USB t...
According to AN2606 section 12 we can use USB DFU bootloader as long we have HSE using a 24, 18, 16, 12, 8, 6, 4 MHz crystal. This is missing from section 3.3 of the datasheet. Is there a reason for this?
Evaluating the STM32F070RBT6 for a project, and using STM32CubeMX V6.10 I am unable to connect the PLL to the HSI RC. It all works ok if I use HSE.I'm wondering what I'm doing wrong. 
We have PCB assemblies built that contain STM324L7 with 1M and 2M flash memory. How can we determine the flash memory size using a JTAG connection (e.g. by reading a register value)?
