[U-Boot-Users] PATCH: IBM PPC440GX: Run interrupts in Native 440GX Mode
by Travis Sawyer 14 Mar '04

14 Mar '04

Greetings: Attached please find the patch to support native interrupt mode for the ibm 440gx. Previously it was running in 440GP compatibility mode. Tested on IBM ref. platform (ocotea, patch pending), and XPedite1000 ChangeLog: Travis Sawyer, 9 March 2004 Change 440GX interrupt mode to native GX mode from GP compatibility mode. This speeds up interrupt processing. -travis

[U-Boot-Users] Patch: Changes to support GCC 3.3.x
by Yuli Barcohen 14 Mar '04

[U-Boot-Users] PATCH: strswab
by Leon Kukovec 14 Mar '04

14 Mar '04

Hi Wolfgang, I've decided to split the PXA IDE/PCMCIA/CF patch into several smaller ones. Here's the patch that adds strswab functions and updates ide_ident() accordingly. The CROSS_COMPILE variable in Makefile you can reject if you think it's not needed. I do not have a shell environment variable CROSS_COMPILE and it turned out that dirname was barking - CROSS_COMPILE in my environment is only set in the Makefile. Fixes: o IDE firmware and model number are shown correctly on little endian machines Changes: o added strswab function which swaps adjacent odd and even bytes in a NUL-terminated string o fixed IDE LBA capacity, device firmware and model number on little endian machines Any issues, let me know. -- Best Regards, Leon.

[U-Boot-Users] Patch generalizing USB driver for MPC5200
by Reinhard Meyer 14 Mar '04

14 Mar '04

1. This spatch removes the compiler warnings (integer made from pointer without cast) 2. it generalizes the Clock Divider Values and the Port Config for USB if CONFIG_USB_CDMFDC5xxx and CONFIG_USB_GPSCFG5xxx are NOT defined, nothing changes. Defining them allows for other system clocks than 528 MHz and/or other types of USB Port Configurations, for example single ended (#define CONFIG_USB_GPSCFG5xxx 0x00005000) Thanks, Pierre, for the good work, the driver works fine on our board!

[U-Boot-Users] Patch: flash_write return value in saveenv
by Eisenhut, Daniel (MED) 13 Mar '04

13 Mar '04

In the CFG_ENV_ADDR_REDUND version of the function saveenv in common/env_flash.c... If there is a failure with the flash_write function it will always display an error message for a Flash Timeout regardless of what the actual error is. The variable "rc" is set to 1 at declaration and flash_perror(rc) is called if there is an error, but the actual return value of flash_write is not stored in rc, therefore the error code displayed will always be 1. The below patch corrects this...

[U-Boot-Users] 16C552 parallel port initialization problems in u-boot
by Sam Song 13 Mar '04

13 Mar '04

Hi, I am working adding support of parallel port of ST16C552 in u-boot but have some weird initialization problems.So I list my related programs and questions as follows for any further help. ***Problems*** 1. How come board_parallel_init became invalid when I put it in lib_ppc/board.c board_init_f() for debugging? 2. Why could I only get 0x00 or 0xff initialization results for the parallel port-PD0-PD7 when I changed par_port->pr1 in ns16552.c as different values like 0x55 or 0xAA?It seemed that the PR register only accpected 0x00 or 0xff as it's first value.But I could change it's value correctly by u-boot command. 3. What's meaning of "__attribute__ ((packed))" in NS16552 structure definition?I copyed it from ns16550.h but don't understand it's function. ***16C552 parallel port register content*** u-boot>md fa010000 fa010000: ff67e0e0 ff67e0e0 ff67e0e0 ff67e0e0 .g fa010010: ff67e0e0 ff67e0e0 ff67e0e0 ff67e0e0 .g u-boot>mm.b fa010000 fa010000: ff ? 55 fa010001: 67 ? 55 fa010002: e0 ? e4 fa010003: e4 ? e4 fa010004: 55 ? . u-boot>md fa010000 fa010000: 5567e4e4 5567e4e4 5567e4e4 5567e4e4 Ug. fa010010: 5567e4e4 5567e4e4 5567e4e4 5567e4e4 Ug. u-boot> When setting 'par_port->pr1 = 0xAA' ,it displayed: fa010000: ff67e0e0 ff67e0e0 ff67e0e0 ff67e0e0 ***Program*** [MYBOARD.h] /*------------------------------------- * NS16552 PRINTER PORT Configuration */ #define CFG_PORT_BASE 0xFA010000 #define CFG_NS16552 #define CONFIG_PARALLEL #define CFG_NS16552_PORT CFG_PORT_BASE #ifdef CONFIG_PARALLEL #define CFG_BR6_PRELIM 0xFA010401 /* REGISTER CS6 */ #define CFG_OR6_PRELIM 0xFFFF0040 #endif [include/ns16552.h] #ifdef CONFIG_PARALLEL /* Sam */ struct NS16552 { unsigned short pr0; /* 0 */ unsigned short sr; /* 1 */ unsigned short com; /* 2 */ } __attribute__ ((packed)); #endif #define pr1 pr0 #define iosel sr /* Sam */ #define con com void NS16552_init (NS16552_t par_port); [driver/ns16552.c] #include <config.h> #ifdef CFG_NS16552 #include <ns16552.h> void NS16552_init (NS16552_t par_port) { par_port->iosel = 0x55; par_port->pr1 = 0xFF; par_port->con = (CON_LOGIC3 | CON_LOGIC2 | ~CON_INTP | CON_INIT ); } #endif [driver/parallel.c] #include <ns16552.h> static NS16552_t port = (NS16552_t) CFG_NS16552_PORT; int parallel_init (void) { NS16552_init (port); return (0); } [lib_ppc/board.c] #include <config.h> --In board_init_r()--- #if defined(CONFIG_MYBOARD) board_parallel_init(); #endif Sorry for disturbing your nice weekend by many questions!Thanks in advance!

Re: [U-Boot-Users] Newbie needs help with RAMDISK
by Luke Fimmerzane 12 Mar '04

12 Mar '04

Sorry for the wrong posting. Because I was slavely following the set-up in the book I referred to in my earlier email for configuring u-boot and running the root file system from RAM disk, I thought someone else might also have followed the same path and might have indicated whether it worked for them or not. The info in the book suggested that as long as you did a bootm <kernel address> <RAM disk address> it should work. I've also read this in the README but I think its only in the context of PPC. I do have ext2 configured in my kernel but maybe I need other options also enabled. (What kind of message should I get if its not enabled) Also what kernel command line should I use? Is root =/dev/ram correct? Do I have to set-up a u-boot envionment variable for a RAM disk? I don't have access to the hardware for the next few days so can't send the full error message list you mentioned. But I want to prepare as much as possible.

Looking u-boot tree, I see that that u-boot doesn't support IPMI. For my board MPC8280 based it's necessary introduce it in order to be used in ATCA shelf for boot and pre-boot phases. At the end of work I'll submit a patch with support for IPMI using SMBUS (i2c). Does anybody is interested to this ???? thanks Enzo ---------------------------------------------------------------------------- -- Figini Enzo senior software engineer Italtel S.p.A. via G.Reiss Romoli Castelletto di Settimo M. - Milano - 20019 - Italy phone : +39 2 4388 8774 mobile : +39 2 4388 9793 www.italtel.it

[U-Boot-Users] MPC8245 help needed.....

Dear all, I am fighting with a custom MPC8245 board and u-boot. However, I can't get any message from the on chip serail port. I notice the u-boot initialization serquence from the source code. It contain a lot of initail sub-routine, get_clocks, init_timebase, env_init, init_baudrate, serial_init, console_init_f, display_options, checkcpu, etc.. My question is that does the on chip serial port show the U-Boot_version message after U-boot finish the console initialization, if my configuration is correct (even some initalization sub-routines behind the console initialization is going wrong)? I focus on my memory initializtion first, because I assume the serial port will output some messages after the serial port initializtion finish. Any advice?
