Not yet, but asked for their datasheet and comparing it to the RT5350 Preliminary datasheet, trying to sort things out like you do! Yes, LINK0-4 are the 5 link status LED pins, but these can also be used for bootstrapping configuration and as standard GPIO #22-26, respectively, see table 1-4 in RT5350 datasheet. Regarding the remainging pins, according to same table: - GPIO #17-21 also correspond to the JTAG pins - UART_TX and UART_RX are probably GPIO #15-16, respectively - GPIO #11-12 are clearly identified as such in the pinout - I2SCLK can only be GPIO #7, according to table 1-5 - SPI_CS1 is GPIO #27, and SP_CLK, SPI_MOSI and SPI_MISO are GPIO #4-6, respectively (GPIO #3 is SPI_CS0 and is probably used onboard for selecting the SPI Flash chip) - I2C_SD and I2C_SCLK are GPIO #1-2, respectively CPURST_N is probably PORST_N and WLAN_LED is WLAN_LED_N. This leaves GPIO #0, GPIO #8-10 and GPIO #13-14 to implement TopLink pins PWR_LED, SECU_LED, RST_PBC, WPS_LED and WPS_PBC. These can probably be guessed by probing using /sys/class/gpio. -Michel > > On Mon, Apr 8, 2013 at 6:24 PM, Drasko DRASKOVIC > <[email protected]> wrote: >> Yes, >> I have seen these boards and contacted suppliers. they seem really >> responsive. >> >> I am missing some more flash though. 8MB is just enough, but it seems >> like RT5350 chipset does not support more. >> >> John, >> do you know what would be the best way to augment flash on these?
