Posted on June 18, 2018 at 09:55Hi I'm trying to use the SPI1 bootloader on a STM32F411.
After I apply power, I set the boot pins to system memory and reset the device.
After reset I take SPI1_NSS low and write the SPI synchronisation commands.
The MISO data from the MCU stays low.
Has anyone any ideas what I am missing?
Thanks in advance
Dave
