Thanks for posting the patch. I ran into this, it was occuring much more frequently in RELEASE builds (code is more optimized, runs faster) on an H730 running at 520Mhz. It took ages to track down the problem and sure enough I had an issue with the ...

I created a case with ST tech support, reference 00130370 and made the following recommendations of things that need fixing:1 - CubeMX code generation - the clock for the OCTOSPIM peripheral is not enabled.2 - AN5050 Octo-SPI interface on STM32 micro...

Success. After enabling the clock as per the solution in my post above I was able to use the flash chip on the IO4-7 lines in memory mapped mode.Thanks again for the replies Andreas!

Success!Thanks a million for point me at that register, I doubt I would ever have found it.The workaround/solution is:RCC->AHB3ENR |= RCC_AHB3ENR_IOMNGREN; ... if (HAL_OSPIM_Config(&hospi1, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_...
