I get it worked with 1B (1bit). Why 4B cannot use? is there a IDE bug inside?

LWIP and FREERTOS undefined reference after HTTPD is enabled

STM32CubeIDE official example: FATFS + 16/32GB SD card returns FR_NOT_READY

Use Ethernet on nucleo STM32F767zi without RTOS

the Pinout and Configuration .ioc is wrong

write a config to STEVAL-MKI220V1 (sensor = LPS27HHTW) with address 0x5C, but 0x5D also gets it
