Resolved! Confused over correct connections for BOOT0, NRST and SWD.
Hi, I'm working on a custom board which I've been programming with an ST-LINK V2 using the SWCLK and SWDIO lines. I mistakenly left BOOT0 floating, but I need to order more boards, so I'm going to correct this mistake.My question: Am I right in think...
Resolved! STM32L4P5G-DK OSPI speed gets too slow at ClockPrescaler = 0;
Hello, I set 120MHz to OCTOSPI for Octo-SPI PSRAM. With the ClockPrescaler 0x02, the PSRAM test takes several seconds. However, with the ClockPrescaler 0x00, it takes over 3 minutes. Does it mean any problem on the clock configuration of STM32CubeIDE...
