Supported features are : + + - Serial terminal support + - Onboard NOR Flash + - Ethernet via the seperate debug board + - Tested on Rev4 and Rev5 boards + + It has also been tested to work correctly when built with a 'standard' GCC +3.2.1 cross-compiler as well as Montavista Linux CEE 3.1's toolchain. + + + +Hardware Configuration : + + The main dips on the P2 board should be set to 2,3,7 and 9 on with all +others off. On the debug board, dips 1 and 7 should be on with the rest off. +The serial console has been set up to run from the DB9 connector on the +P2 board at 115200 baud, 8 data bits, no stop bits, 1 parity bit. + + It should be noted that the P2 board has NOR flash that is addressable via +either CS0 or CS3. This mode can be changed via DIP9 on the P2 board. + + + +Installing u-boot for the P2 : + + You can simply build u-boot for the Perseus by following the instructions +in the main readme file. The target configuration is "omap730p2_config". +Once u-boot has been built, you should strip the executable so it can be +loaded via CCS (which cant cope with the symbols in the ELF binary) : + $ cp u-boot u-boot.out + $ arm-linux-strip u-boot.out + + The method we've used for installing u-boot the first time on a P2 is +as follows : + +1) Configure TI Code Composer Studio to connect to the P2 board via JTAG + as described in the Users Guide. + +2) Set up the P2 to boot from CS3, and connect with CCS. Reset the CPU + and run the "init_mmu" GEL script. + +3) Use the "Load Program" option to send the u-boot.out file to the P2 and + run. + + At this point, u-boot should run and you will see the boot menu on your +serial terminal. You can then load the u-boot image to memory : + + # loadb 0x10000000 + + Send the "u-boot.bin" binary via the serial using Kermit. Once loaded +you can self-flash u-boot : + + # protect off 1:0 + # erase 1:0 + # cp.b 0x10000000 0x0 0x20000 + + You should now be able to reset the board and run u-boot from flash. + + + +Alternative flash option : + + Sometimes, if you've been silly, you can get the board into a state where +whats in flash has upset the board so much that you can no longer connect +to the P2 via JTAG. However, you can set DIP9 to off to swap the boot mode +of the P2 so that you boot from RAM instead of NOR flash. This moves NOR +flash up to 0x0C000000. You can build a special version of u-boot to +utilise this by the following config : + + $ make omap730p2_cs0boot_config + + If you load this up via CCS it will detect flash at its alternate location +and allow you to programme your u-boot image (which, remember must be built +for CS3 boot!) Once you do this, you can revert to CS3 boot and it will work +fine again. + + + +Errata : + +1) It's been observed that sometimes the tftp transfer of kernels to the + board can have checksum errors or stall. This appears to be an issue + with the lan91c96.c driver, and can normally be worked around by + resetting the board and trying again. diff --git a/drivers/lan91c96.c b/drivers/lan91c96.c index 032f978..c3b715c 100644 --- a/drivers/lan91c96.c +++ b/drivers/lan91c96.c @@ -620,7 +620,7 @@ static int smc_open (bd_t *bd) address |= smc_mac_addr[i]; SMC_outw (address, LAN91C96_IA0 + i); } -#else +#else for (i = 0; i < 6; i++) SMC_outb (smc_mac_addr[i], LAN91C96_IA0 + i); #endif @@ -937,7 +937,7 @@ int smc_get_ethaddr (bd_t * bd) return (0); } -/* +/* * get_rom_mac() * Note, this has omly been tested for the OMAP730 P2. */ @@ -960,6 +960,4 @@ int get_rom_mac (char *v_rom_mac) #endif } - - #endif /* CONFIG_DRIVER_LAN91C96 */ diff --git a/drivers/ns16550.c b/drivers/ns16550.c index 05862ee..f9fe819 100644 --- a/drivers/ns16550.c +++ b/drivers/ns16550.c @@ -26,7 +26,7 @@ void NS16550_init (NS16550_t com_port, int baud_divisor) com_port->lcr = LCRVAL; com_port->mcr = MCRVAL; com_port->fcr = FCRVAL; -#if defined(CONFIG_OMAP1510) || defined(CONFIG_OMAP1610) +#if defined(CONFIG_OMAP1510) || defined(CONFIG_OMAP1610) || defined(CONFIG_OMAP730) com_port->mdr1 = 0; /* select uart mode */ #endif } diff --git a/include/configs/h2_p2_dbg_board.h b/include/configs/h2_p2_dbg_board.h new file mode 100644 index 0000000..8a5ec34 --- /dev/null +++ b/include/configs/h2_p2_dbg_board.h @@ -0,0 +1,145 @@ +/* + * + * BRIEF MODULE DESCRIPTION + * TI H2 and P2 Debug Board hardware map + * + * Copyright (C) 2004 MPC-Data Limited.
