Hello,we have a STM32MP157C processor MAC connected to MAX24287 PHY by RGMII interface, what we see that the GTX_CLK duty-cycle higher than 55%Could we decrease this value somehow?Thank you.Zsolt
My goal is to use USART6 as debug output because I haven't route the dedicated BootROM pins of the USART2.Anyway! It seems that the BootROM is trying to read my SD card. First sequence:CMD and CLK of SDMMC1 seems to be talking to the SD card in a ver...
