Added Core I2C connections Things to change for Revision 1.0 Peripherial reset will now only be Ethernet reset Untangle Console lines Isolated console needs 15V maybe work to run on 3.3V This information provided by Brent in an email of 27 march 2015 GPIO - Function 0 - BOOT0 1 - BOOT1 2 - BOOT2 3 - Ethernet controller IRQ (input) 4 - Ethernet controller PME (input) 5 - SD_CARD_CLK 6 - SD_CARD_CMD 7 - SD_CARD_D0 8 - SD_CARD_D1 9 - SD_CARD_D2 10 - SD_CARD_D3 GPIO 11-18 initially read 0000, then serve as RS-232 driver enable outputs 11 - Unused 12 - Unused 13 - Enable RS-232 channel 3 - AM 1 14 - Enable RS-232 channel 4 - AM 2 15 - Enable RS-232 channel 5 - AM 3 16 - GPIO RS-232 channel 6 17 - GPIO RS-232 channel 7 18 - GPIO RS-232 channel 8 19 - HS_USB_POWER_ON (power on HIGH) (output) 20 - CPU busy LED (1 = ON) B_N_STCS0 - UART_CS B_N_STCS1 - ENET_CS NAND_NCS0 - unused - Does not come off module NAND_NCS1 - unused NAND_NCS2 - HS_USB_OVERCURRENT (input) NAND_NCS3 - RTC_INT_N (input) NAND_RDBYN0 - unused - Does not come off module NAND_RDBYN1 - unused NAND_RDBYN2 - unused NAND_RDBYN3 - Octal UART IRQ I2SRX_BCK0 - Ethernet Reset (active low with pull-up) - no longer also resets UART and RTC I2C-SDA0 - CoreSDA I2C-SCL0 - CoreSCK PERIPHERIAL_RESET - Connects I2SRX_BCK0 to resets of Ethernet, UART and RTC. Orange wire. Requies R65 to be not Installed Requires UART pin to be lifted and wire soldered to the lifted pin SD card carrier pinout is upside down R19 to SD card switch needs to be pulled to constant 3.3V Isolated concole needs 15V J16 added Untangled Console Rs-232 connector ****Make sure the isolated console port lines are corrected Brent would like to have these pins moved around... The LED -- EA board uses GPIO2, ESP board uses GPIO20 The ethernet interrupt -- EA uses NAND_RDBYN3, ESP uses GPIO3 USB overcurrent interrupt -- EA uses I2SRX_WS0, ESP uses NAND_NCS2 Revision 0 pin usage 0 - BOOT0 1 - BOOT1 2 - BOOT2 3 - Ethernet controller INT (input) 4 - Ethernet controller PME (input) 5 - SD_CARD_CLK 6 - SD_CARD_CMD 7 - SD_CARD_D0 8 - SD_CARD_D1 9 - SD_CARD_D2 10 - SD_CARD_D3 11 - RS-232 ch 1 Buffer power (Power on HIGH) (output) (read of pin = 0) 12 - RS-232 ch 2 Buffer power (Power on HIGH) (output) (read of pin = 0) 13 - RS-232 ch 3 Buffer power (Power on HIGH) (output) (read of pin = 0) 14 - RS-232 ch 4 Buffer power (Power on HIGH) (output) (read of pin = 0) 15 - RS-232 ch 5 Buffer power (Power on HIGH) (output) (read of pin = 0) 16 - RS-232 ch 6 Buffer power (Power on HIGH) (output) (read of pin = 0) 17 - RS-232 ch 7 Buffer power (Power on HIGH) (output) (read of pin = 0) 18 - RS-232 ch 8 Buffer power (Power on HIGH) (output) (read of pin = 0) 19 - HS_USB_POWER_ON (power on HIGH) (output) 20 - LED (1 = ON) B_N_STCS0 - UART_CS B_N_STCS1 - ENET_CS NAND_NCS0 NAND_NCS1 NAND_NCS2 - HS_USB_OVERCURRENT (input) NAND_NCS3 - RTC_INT_N (input) NAND_RDBYN0 NAND_RDBYN1 NAND_RDBYN2 NAND_RDBYN3 - UART Interrupt (input) Ethernet chips CMD line is connected to Address 1 I need where to connect PME of the ethernet chip - GPIO RTC Interrup output, what to do? - GPIO For the purpose of Host recognizing it is in this card GPIO11-18 read all 0 GPIO usage: 0 - BOOT0 1 - BOOT1 2 - BOOT2 3 - UART Interrupt (input) 4 - HS_USB_POWER_ON (power on HIGH) (output) 5 - SD_CARD_CLK 6 - SD_CARD_CMD 7 - SD_CARD_D0 8 - SD_CARD_D1 9 - SD_CARD_D2 10 - SD_CARD_D3 11 - RS-232 ch 1 Buffer power (Power on HIGH) (output) (read of pin = 0) 12 - RS-232 ch 2 Buffer power (Power on HIGH) (output) (read of pin = 0) 13 - RS-232 ch 3 Buffer power (Power on HIGH) (output) (read of pin = 0) 14 - RS-232 ch 4 Buffer power (Power on HIGH) (output) (read of pin = 0) 15 - RS-232 ch 5 Buffer power (Power on HIGH) (output) (read of pin = 0) 16 - RS-232 ch 6 Buffer power (Power on HIGH) (output) (read of pin = 0) 17 - RS-232 ch 7 Buffer power (Power on HIGH) (output) (read of pin = 0) 18 - RS-232 ch 8 Buffer power (Power on HIGH) (output) (read of pin = 0) 19 - Ethernet controller PME (input) 20 - Ethernet controller INT (input)
