The only difference concerns key naming. There are 4 -keys on TRAB: 1, 2, 3, 4. - -1) The "kbd" command provides information about the current state of - the keys. For example, - - TRAB # kbd - Keys: 1 0 1 0 - - means that keys 1 and 3 are pressed. The keyboard status is also - stored in the "keybd" environment variable. In this example we get - - keybd=1010 - -2) The "preboot" variable is set according to current environment - settings and keys pressed. This is an example: - - TRAB # setenv magic_keys XY - TRAB # setenv key_magicX 12 - TRAB # setenv key_cmdX echo ## Keys 1 + 2 pressed ##\;echo - TRAB # setenv key_magicY 13 - TRAB # setenv key_cmdY echo ## Keys 1 + 3 pressed ##\;echo - - Here "magic_keys=XY" means that the "key_magicX" and "key_magicY" - variables will be checked for a match. Each variable "key_magic*" - defines a set of keys. In the our example, if keys 1 and 3 are - pressed during reset, then "key_magicY" matches, so the "preboot" - variable will be set to the contents of "key_cmdY": - - preboot=echo ## Keys 1 + 3 pressed ##;echo - -3) The TRAB board has optional modem support. When a certain key - combination is pressed on the keyboard at power-on, the firmware - performs the necessary initialization of the modem and allows for - dial-in. The key combination is specified in the - "include/configs/trab.h" file. For example: - - #define CONFIG_MODEM_KEY_MAGIC "23" - - means that modem will be initialized if and only if both keys 2, 3 - are pressed. Note that the format of this string is similar to the - format of "key_magic*" environment variables described above. diff --git a/board/trab/auto_update.c b/board/trab/auto_update.c deleted file mode 100644 index bcb8505..0000000 --- a/board/trab/auto_update.c +++ /dev/null @@ -1,676 +0,0 @@ -/* - * (C) Copyright 2003 - * Gary Jennejohn, DENX Software Engineering, garyj@denx.de. - * - * See file CREDITS for list of people who contributed to this - * project. - * - * This program is free software; you can redistribute it and/or - * modify it under the terms of the GNU General Public License as - * published by the Free Software Foundation; either version 2 of - * the License, or (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Then test the address - * lines. Finally, test the cells in the memory now that the test - * program knows that the address and data lines work properly. - * This sequence also helps isolate and identify what is faulty. - * - * o For the address line test, it is a good idea to use the base - * address of the lowest memory location, which causes a '1' bit to - * walk through a field of zeros on the address lines and the highest - * memory location, which causes a '0' bit to walk through a field of - * '1's on the address line. - * - * o Floating buses can fool memory tests if the test routine writes - * a value and then reads it back immediately. The problem is, the - * write will charge the residual capacitance on the data bus so the - * bus retains its state briefely. When the test program reads the - * value back immediately, the capacitance of the bus can allow it - * to read back what was written, even though the memory circuitry - * is broken. To avoid this, the test program should write a test - * pattern to the target location, write a different pattern elsewhere - * to charge the residual capacitance in a differnt manner, then read - * the target location back. - * - * o Always read the target location EXACTLY ONCE and save it in a local - * variable. The problem with reading the target location more than - * once is that the second and subsequent reads may work properly, - * resulting in a failed test that tells the poor technician that - * "Memory error at 00000000, wrote aaaaaaaa, read aaaaaaaa" which - * doesn't help him one bit and causes puzzled phone calls. Been there, - * done that. - * - * Data line test: - * --------------- - * This tests data lines for shorts and opens by forcing adjacent data - * to opposite states. Because the data lines could be routed in an - * arbitrary manner the must ensure test patterns ensure that every case - * is tested. By using the following series of binary patterns every - * combination of adjacent bits is test regardless of routing. - * - * ...101010101010101010101010 - * ...110011001100110011001100 - * ...111100001111000011110000 - * ...111111110000000011111111 - * - * Carrying this out, gives us six hex patterns as follows: - * - * 0xaaaaaaaaaaaaaaaa - * 0xcccccccccccccccc - * 0xf0f0f0f0f0f0f0f0 - * 0xff00ff00ff00ff00 - * 0xffff0000ffff0000 - * 0xffffffff00000000 - * - * To test for short and opens to other signals on our boards, we - * simply test with the 1's complemnt of the paterns as well, resulting - * in twelve patterns total. - * - * After writing a test pattern. a special pattern 0x0123456789ABCDEF is - * written to a different address in case the data lines are floating. - * Thus, if a byte lane fails, you will see part of the special - * pattern in that byte lane when the test runs. For example, if the - * xx__xxxxxxxxxxxx byte line fails, you will see aa23aaaaaaaaaaaa - * (for the 'a' test pattern). - * - * Address line test: - * ------------------ - * This function performs a test to verify that all the address lines - * hooked up to the RAM work properly. If there is an address line - * fault, it usually shows up as two different locations in the address - * map (related by the faulty address line) mapping to one physical - * memory storage location. The artifact that shows up is writing to - * the first location "changes" the second location. - * - * To test all address lines, we start with the given base address and - * xor the address with a '1' bit to flip one address line. For each - * test, we shift the '1' bit left to test the next address line. - * - * In the actual code, we start with address sizeof(ulong) since our - * test pattern we use is a ulong and thus, if we tried to test lower - * order address bits, it wouldn't work because our pattern would - * overwrite itself. - * - * Example for a 4 bit address space with the base at 0000: - * 0000 <- base - * 0001 <- test 1 - * 0010 <- test 2 - * 0100 <- test 3 - * 1000 <- test 4 - * Example for a 4 bit address space with the base at 0010: - * 0010 <- base - * 0011 <- test 1 - * 0000 <- (below the base address, skipped) - * 0110 <- test 2 - * 1010 <- test 3 - * - * The test locations are successively tested to make sure that they are - * not "mirrored" onto the base address due to a faulty address line. - * Note that the base and each test location are related by one address - * line flipped. Note that the base address need not be all zeros. - * - * Memory tests 1-4: - * ----------------- - * These tests verify RAM using sequential writes and reads - * to/from RAM. There are several test cases that use different patterns to - * verify RAM. Each test case fills a region of RAM with one pattern and - * then reads the region back and compares its contents with the pattern. - * The following patterns are used: - * - * 1a) zero pattern (0x00000000) - * 1b) negative pattern (0xffffffff) - * 1c) checkerboard pattern (0x55555555) - * 1d) checkerboard pattern (0xaaaaaaaa) - * 2) bit-flip pattern ((1 << (offset % 32)) - * 3) address pattern (offset) - * 4) address pattern (~offset) - * - * Being run in normal mode, the test verifies only small 4Kb - * regions of RAM around each 1Mb boundary. For example, for 64Mb - * RAM the following areas are verified: 0x00000000-0x00000800, - * 0x000ff800-0x00100800, 0x001ff800-0x00200800, ..., 0x03fff800- - * 0x04000000.
