Hi all,I would like to ask if there is a suggested procedure to move the network weights, the one generated inside network_data.h, to external memory-mapped QSPI FLASH. I've already moved both input/output data and activation to external SRAM, but I'...

Dear @Francois VILMAIN ,And that's the missing piece!Coming from F4s I've always used LL_ADC_REG_StartConversionExtTrig( ADC1, ExternalTrigger). Not seeing the function inside the library I've thought that it was not necessary anymore, but of course...
