The RCW directories names for the LS1043AQDS boards conform to the following naming convention: ab_cdef_g: a = 'R' indicates RGMII1@DTSEC3 is supported b = 'R' indicates RGMII2@DTSEC4 is supported 'N' indicates not available/not used c = What is available in Slot 1 or SPF cage d = What is available in Slot 2 e = What is available in Slot 3 f = What is available in Slot 4 For the Slots (c..f): 'N' is NULL, not available/not used 'P' is PCIe 'X' is XAUI 'S' is SGMII 'Q' if QSGMII 'F' is XFI 'H' is SATA 'A' is AURORA For the srds_prtcl (g): g = 'hex value of serdes1 protocol value' So RR_FQPP_1455 means: - RGMII1@DTSEC3 on board - RGMII2@DTSEC4 on board - XFI on SFP cage - QSGMII on Slot 2 - PCIe2 on Slot 3 - PCIe3 on Slot 4 - SERDES1 Protocol is 0x1455 BIN Core/Platform/FMan/DDR Bin1: 1500MHz/400MHz/500MHz/1600MT/s Bin2: 1400MHz/300MHz/500MHz/1600MT/s Bin3: 1200MHz/300MHz/500MHz/1300MT/s Files naming convention ============================= rcw_x.rcw rcw_x_bootmode.rcw rcw_x_specialsetting.rcw x = Core frequency bootmode = bootmode:SD/NAND/NOR and so on. specialsetting = special setting: lpuart:used for lpuart sben:Secure boot For example, rcw_1600.rcw means rcw for core frequency of 1600MHz with nor boot. rcw_1600_sd.rcw means rcw for core frequency of 1600MHz with sd boot. rcw_1600_lpuart.rcw means rcw for core frequency of 1600MHz with nor boot special for lpuart.
