https://community.nxp.com/t5/Layerscape/Programming-LS1046ARDB-Ethernet-with-32bit-RTOS/m-p/1588336#M11764 <P>I'm trying to program Ethernet port (independent mode) for an RTOS. The RTOS I use is 32-bit. U-boot is used to load the RTOS.</P><P>For Ethernet program, I understand that I need to load FMAN microcode.&nbsp; I guess, FMAN microcode can work with 32-bit access. But, when I check the&nbsp;LS1046A Reference manual, it says QMAN S/W Portal (05_0000_0000) is not supported for 32-bit access. Does FMAN microcode uses this QMAN S/W portal? Does this mean microcode/Ethernet port cannot be programmed with 32-bit RTOS?</P><P>Thanks in advance for any tips/information.</P> Thu, 26 Jan 2023 14:26:08 GMT srak 2023-01-26T14:26:08Z https://community.nxp.com/t5/Layerscape/Programming-LS1046ARDB-Ethernet-with-32bit-RTOS/m-p/1588336#M11764 <P>I'm trying to program Ethernet port (independent mode) for an RTOS.
