[U-Boot-Users] ppc4xx/serial.c
by Seingier François-Xavier 12 Jul '04

12 Jul '04

hello, I've been going through the code of the function serial_init because I couldn't get the proper baudrate divisor. I must admit I don't understand the operations made to calculate udiv and bdiv... According to the 405gp user manual, these are the meanings of a few parameters. CFG_BASE_BAUD = SerClk / 16 bdiv = SerClk / (16 * baudrate) SerClk = cpu_freq / udiv As a result, udiv and bdiv should be generated as follows in serail_init: if external_clock: SerClk = CFG_EXT_SERIAL_CLK udiv = 1 else: SerClk = CFG_BASE_BAUD * 16 udiv = cpu_freq / serClk endif bdiv = SerClk / (16 * baudrate) Am I missing something? regards, François-Xavier SEINGIER

[U-Boot-Users] [PATCH] docecc.c include line
by Eisenhut, Daniel (MED) 11 Jul '04

11 Jul '04

The file common/docecc.c includes linux/mtd/doc2000.h prior to checking if CFG_CMD_DOC is used. This defines SECTORSIZE, ADDR_COLUMN, etc that is also being defined by various include/configs/* files for use with NAND. This causes an annoying compiler warning due to redefinition. Attached patch moves the #include line until after the check for CFG_CMD_DOC to prevent warning message. * Patch by Dan Eisenhut, 01 Jul 2004: Moved docecc.c include line to prevent compiler warning on some boards. Probably a bigger issue here with conflicting macro variables, just no one has used CMD_DOC and CMD_NAND at the same time yet.

[U-Boot-Users] New command loopw
by Martin Krause 11 Jul '04

11 Jul '04

Hello all, here is a patch, which adds a new memory command 'loopw'. In difference to the existing 'loop' command, which implements a read loop, 'loopw' writes to memory in an infinite loop. We use this command to do hardware qualifications on our boards like memory timing measurements with a scope or a logic analysator. To not increase the memory footprint of the default U-Boot configuration, 'loopw' is only compiled in if CONFIG_LOOPW is defined. * Patch by Martin Krause, 29 June 2004: Add new memory command: loopw - infinite write loop on address range Best regards, Martin Krause ------------------------------------------------------------------ Martin Krause TQ-Systems GmbH Gut Delling, Mühlstr. 2, 82229 Seefeld, Germany Email: martin.krause(a)tqs.de http://www.tq-group.com <<patch_u-boot_loopw_command>>

[U-Boot-Users] What are IBAT and DBAT?
by Shawn 11 Jul '04

11 Jul '04

Hi, When trying to port u-boot to a MPC8245 card, I'm not sure what IBAT and DBAT register work for. For example, sl8245.h defines 4 regions of IBAT: SDRAM_BASE, 0x40000000, 0x80000000, and 0xf0000000. 1. Why are these regions defined? 2. Does it mean that you cannot access that memory area if the area hasn't been set by configuring IBAT and DBAT accordingly? 3. Can IBAT and DBAT be modified dynamically? For example, if I want to access 0x70000000 ~ 0x78000000 temporarily, which is not defined in configuration header file, can I change the configuration of one of IBAT and DBAT pair, e.g. ibat2 and dbat2?
