Honored ContributorThanks. It occurred to me that I should have pointed out that my analysis was for the AX027 part vs. SX027. If anyone has heard of someone designing a board that can accommodate either SX or GX parts, I'd be interested in their experience.
Also, if anyone is interested, here are the pins that are different: AX027 SX027 PIN GND VCCIO_HPS H13 GND VCCIOREF_HPS J13 GND VCCL_HPS K14 GND VCCL_HPS L13 GND VCCL_HPS L14 GND VCCL_HPS M13 GND VCCPLL_HPS J14 NC GPIO2_IO0,NAND_ADQ0,SDMMC_DATA0,QSPI_CLK F12 NC GPIO2_IO1,NAND_ADQ1,SDMMC_CMD,QSPI_IO0 G16 NC GPIO2_IO10,NAND_ADQ4,UART1_CTS_N,SDMMC_DATA6,SPIM0_SS0_N,EMAC2_MDIO,I2C_EMAC2_SDA E12 NC GPIO2_IO11,NAND_ADQ5,UART1_RX,SDMMC_DATA7,SPIS0_CLK,EMAC2_MDC,I2C_EMAC2_SCL G15 NC GPIO2_IO12,NAND_ADQ6,UART1_TX,QSPI_SS2,SPIS0_MOSI,EMAC0_MDIO,I2C_EMAC0_SDA K15 NC GPIO2_IO13,NAND_ADQ7,UART1_RX,QSPI_SS3,SPIS0_SS0_N,EMAC0_MDC,I2C_EMAC0_SCL F13 NC GPIO2_IO2,NAND_WE_N,SDMMC_CCLK,QSPI_SS0,BOOTSEL2 D12 NC GPIO2_IO3,NAND_RE_N,SDMMC_DATA1,QSPI_IO1 J12 NC GPIO2_IO4,NAND_ADQ2,SDMMC_DATA2,QSPI_IO2_WPN H12 NC GPIO2_IO5,NAND_ADQ3,SDMMC_DATA3,QSPI_IO3_HOLD F14 NC GPIO2_IO6,NAND_CLE,SDMMC_PWR_ENA,SPIM0_SS1_N,SPIS0_MISO,BOOTSEL1 G13 NC GPIO2_IO7,NAND_ALE,QSPI_SS1,SPIM0_CLK,BOOTSEL0 J15 NC GPIO2_IO8,NAND_RB,UART1_TX,SDMMC_DATA4,SPIM0_MOSI,EMAC1_MDIO,I2C_EMAC1_SDA H15 NC GPIO2_IO9,NAND_CE_N,UART1_RTS_N,SDMMC_DATA5,SPIM0_MISO,EMAC1_MDC,I2C_EMAC1_SCL F16 NC HPS_CLK1 G14 NC HPS_nPOR K11 NC HPS_nRST K12
