[U-Boot-Users] Porting to a new board
by Curt Brune 16 Oct '03

16 Oct '03

Hi, I have an ARM7TDMI based board that is not currently supported by u-boot and I would like to have a go at it -- the board is described here: http://www.cucy.net/evb4510.pdf The boot loader that comes with the board is lame. It requires one to connect with a windows program to program the flash and to do other u-boot type things. I want to put u-boot on this board instead. Is there a "new board porting guide" or other porting related docs? Cheers, Curt

[U-Boot-Users] walnut 405gp bridge setting
by Xiaoshan Zuo 15 Oct '03

15 Oct '03

I have a customized walnut 405 gp board. While using u-boot the bridge was not set correclty. The problem was that the bridge didn't respond to requst. The problem was traced down to PCIC0_CMD[MA]=0 on the bridge. The bit is set correclty in pci_405gp_init, later it is got changed in pci_hose_scan_bus. It is not supposed to be changed, as suggested by the comment below in the code. But this comment contradict with function pci_hose_scan_bus which intentionly doesn't skip the bridge. Removing #ifndef in pci_hose_scan_bus makes the bridge work. My question is: is this a typo? Where can I search for u-boot mailing list archive? linuxppc is very easy to serach useful information. Sorry for the newbie question. Thanks, Xiaoshan /* * drivers/pci.c skips every host bridge but the 405GP since it could * be set as an Adapter. * * I (Andrew May) don't know what we should do here, but I don't want * the auto setup of a PCI device disabling what is done pci_405gp_init * as has happened before. */ void pci_405gp_setup_bridge(struct pci_controller *hose, pci_dev_t dev, struct pci_config_table *entry) { #ifdef DEBUG printf("405gp_setup_bridge\n"); #endif } In drivers/pci.c: int pci_hose_scan_bus(struct pci_controller *hose, int bus) { #ifndef CONFIG_405GP /* don't skip host bridge on ppc405gp */ /* Skip our host bridge */ if ( dev == PCI_BDF(hose->first_busno,0,0) ) continue; #endif

[U-Boot-Users] Where does u-boot start when booting Linux?
by Allen Curtis 14 Oct '03

14 Oct '03

I was hoping that someone could give me a quick answer. When u-boot starts Linux, does is start from the beginning for does it jump in somewhere past decompress()? I have been looking at the Linux code and it doesn't appear that the bdinfo structure is being handled correctly for u-boot. There is an CONFIG_EMBEDDEDBOOT option but even this only passes the boot parameter in a few instances. Does u-boot fix this somehow? Another thing is embed_config() for the ADS8260 board, forces the baud-rate to 9600 but 2_4_devel is quite happy at 115200 as in u-boot. This is interesting since I am trying to fix a serial baud-rate problem. TIA!

[U-Boot-Users] SCC Ethernet with PHY BCM522
by Raghu 14 Oct '03

14 Oct '03

Hello All, I have a MPC852T based board. I have configured SCC4 ETHERNET register and I have a PHY ( Broadcom 5222 ) chip as a PHY support. I am able to do a SCC loopback, but the data is not going out from the PHY when I diable the loopback. How do I access the PHY from SCC "scc.c" driver ?? do I have to do this anyway ? The PHY is getting accessed from "MII" i.e I am able to do "mii read/write" The Dual BCM Phy registers are located at 0x10 and 0x11 offset. of PHY. Warm Regards Raghu. __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search http://shopping.yahoo.com

[U-Boot-Users] Enabling the data size parameter for memory commands like "md"?
by Pasi Huhtiniemi 14 Oct '03

14 Oct '03

Hello, I'm playing around with a day-old cvs snapshot of U-Boot, using it with "make at91rm9200dk_config". My problem is the same with 0.4.0. >From the source (and from the usage help) I understand that at least the memory commands like "md" should accept (optional) data size parameter (.b/.w/.l) as the first parameter. How do you enable this? In my environment they don't work: 1) argv[0] is the command itself (like "md"), not the data size parameter from where the source tries to read it and 2) if I give the data size parameter, the upper framework counts the amount of parameters to be illegal and therefore certain commands give me an error message (the short usage). I suppose there is a #define missing? What is it? I could not quickly find it grepping the source, googling the net / mailing list archives. Best Regards, Pasi Huhtiniemi

[U-Boot-Users] Support for ALTERA FPGAs
by Steven Scholz 13 Oct '03

13 Oct '03

Hi there, the patch attached adds support for ALTERA FPGAs. For now only the ACEX1K using the so called "passive serial" Interface. The code and idea is heavily stolen from the xilinx stuff. And just like there the board specific code has to provide some functions for handling the FPGA signals CONF_DONE, DATA, DCLK, nCONFIG, nSTATUS. I thought I release it quite early to avoid redundant work done by others and hope this could be a usefull starting point for people using Altera FPGAs. * Patch by Steven Scholz, 10 Oct 2003 - Add support for Altera FPGA ACEX1K Cheers, -- Steven Scholz imc Measurement & Control imc Meßsysteme GmbH Voltastr. 5 Voltastr. 5 13355 Berlin 13355 Berlin Germany Deutschland fon: +49 30 467090-0 Tel: 030 / 467090-0 fax: +49 30 4631576 fax: 030 / 4631576

[U-Boot-Users] DiskOnChip problem on warm boot
by James Bates 13 Oct '03

13 Oct '03

Hi all, Have had my MPC8260ADS based system up and running for a while now but I have recently noticed a problem when I warm boot. When it comes to detecting the DOC chip I just get a series of 10 "Doc_WaitReady timeout" messages. This takes about a couple of minutes and then it carries on with the boot as normal. Any ideas of what is happening? This does not happen in a power on reset.

hello ! all I'm porting u-boot-0.4.0 to my WindRiver MDP PRO board now,some addressing specifications are listed below.I choose the fads823 as the model.I have vision ICE ii & vision CLICK to program flash and debug the code. I compile the code in the vmware linux environment.After "make myboard_config" and "make",I copy the u-boot(ELF) to the vision CLICK path in windows environment，then Convert to .BIN file, program to flash,run,use the hyperterminal as the console. Now in the cpu_init.c ,I masked all the OR/BR initialization clause,for when I released them there's nothing displayed on the hyperterminal ;but when masked them ,the program can run to the "=>"(after main_loop();)with the vision ICE II and to the relocate_code()(in the board_init_f();)without the visionICE II ,some register value are listed below in the vision CLICK BKM mode. **1.why I cann't initialize the OR/BR registers in the cpu_init.c **2.how to modify the dram initialization to pass the relocate_code() 3.can you tell me something details about the BCSR register in the FADS823 model. 4.are there any better model for WindRiver MDPRRO board ?

Reading of ATA drive id is broken in cmd_ide.c for big endian cpu:s that are not ppc. If I am not mistaken, the text strings should be endian swapped on big endian cpu:s, but not for little ones. * Patch by Thomas Lange, 10 Oct 2003: Endian swap ATA identity for all big endian cpu:s, not just ppc. /Thomas --- u-boot-0.4.8/common/cmd_ide.c 2003-07-01 23:07:07.000000000 +0200 +++ u-boot-0.4.8_new/common/cmd_ide.c 2003-10-08 23:56:06.000000000 +0200 @@ -164,9 +164,6 @@ static uchar ide_wait (int dev, ulong t static void __inline__ ide_outb(int dev, int port, unsigned char val); static unsigned char __inline__ ide_inb(int dev, int port); -#ifdef __PPC__ -static void input_swap_data(int dev, ulong *sect_buf, int words); -#endif static void input_data(int dev, ulong *sect_buf, int words); static void output_data(int dev, ulong *sect_buf, int words); static void ident_cpy (unsigned char *dest, unsigned char *src, unsigned int len); @@ -809,7 +806,13 @@ output_data_short(int dev, ulong *sect_b *pbuf = 0; } # endif /* CONFIG_AMIGAONEG3SE */ +#endif /* __PPC_ */ +/* We only need to swap data if we are running on a big endian cpu. */ +/* But Au1x00 cpu:s already swaps data in big endian mode! */ +#if defined(__LITTLE_ENDIAN) || defined(CONFIG_AU1X00) +#define input_swap_data(x,y,z) input_data(x,y,z) +#else static void input_swap_data(int dev, ulong *sect_buf, int words) { @@ -821,9 +824,7 @@ input_swap_data(int dev, ulong *sect_buf *dbuf++ = ld_le16(pbuf); } } -#else /* ! __PPC__ */ -#define input_swap_data(x,y,z) input_data(x,y,z) -#endif /* __PPC__ */ +#endif /* __LITTLE_ENDIAN || CONFIG_AU1X00 */ #ifdef __PPC__

[U-Boot-Users] [PATCH] cmd_ide.c, ifdef code only needed by 8xx_direct
by Thomas Lange 09 Oct '03

A big chunk of code in cmd_ide.c is only valid for boards that set CONFIG_IDE_8xx_DIRECT That makes it harder than neccesary to follow the flow since alot of calculations/variables are pointless. * Patch by Thomas Lange, 10 Oct 2003: code only needed by CONFIG_IDE_8xx_DIRECT ifdef:ed /Thomas --- u-boot-0.4.8/common/cmd_ide.c 2003-07-01 23:07:07.000000000 +0200 +++ u-boot-0.4.8_new/common/cmd_ide.c 2003-10-09 00:02:42.000000000 +0200 @@ -65,6 +65,7 @@ #if (CONFIG_COMMANDS & CFG_CMD_IDE) +#ifdef CONFIG_IDE_8xx_DIRECT /* Timings for IDE Interface * * SETUP / LENGTH / HOLD - cycles valid for 50 MHz clk @@ -101,6 +102,8 @@ static int pio_mode = CFG_PIO_MODE; #define PCMCIA_MK_CLKS( t, T ) (( (t) * (T) + 999U ) / 1000U ) +#endif /* CONFIG_IDE_8xx_DIRECT */ + /* ------------------------------------------------------------------------- */ /* Current I/O Device */ @@ -180,8 +183,6 @@ ulong atapi_read (int device, ulong blkn #ifdef CONFIG_IDE_8xx_DIRECT static void set_pcmcia_timing (int pmode); -#else -#define set_pcmcia_timing(a) /* dummy */ #endif /* ------------------------------------------------------------------------- */ @@ -472,9 +473,8 @@ int do_diskboot (cmd_tbl_t *cmdtp, int f void ide_init (void) { - DECLARE_GLOBAL_DATA_PTR; - #ifdef CONFIG_IDE_8xx_DIRECT + DECLARE_GLOBAL_DATA_PTR; volatile immap_t *immr = (immap_t *)CFG_IMMR; volatile pcmconf8xx_t *pcmp = &(immr->im_pcmcia); #endif @@ -502,6 +502,7 @@ void ide_init (void) WATCHDOG_RESET(); +#ifdef CONFIG_IDE_8xx_DIRECT /* Initialize PIO timing tables */ for (i=0; i <= IDE_MAX_PIO_MODE; ++i) { pio_config_clk[i].t_setup = PCMCIA_MK_CLKS(pio_config_ns[i].t_setup, @@ -518,6 +519,7 @@ void ide_init (void) pio_config_ns[i].t_length, pio_config_clk[i].t_length, pio_config_ns[i].t_hold, pio_config_clk[i].t_hold); } +#endif /* CONFIG_IDE_8xx_DIRECT */ /* Reset the IDE just to be sure. * Light LED's to show @@ -528,12 +530,12 @@ void ide_init (void) #ifdef CONFIG_IDE_8xx_DIRECT /* PCMCIA / IDE initialization for common mem space */ pcmp->pcmc_pgcrb = 0; -#endif /* start in PIO mode 0 - most relaxed timings */ pio_mode = 0; set_pcmcia_timing (pio_mode); +#endif /* * Wait for IDE to get ready. * According to spec, this can take up to 31 seconds!

[U-Boot-Users] [PATCH] fix ATA for non ppc
by Thomas Lange 09 Oct '03

09 Oct '03

AFAIK, cmd_ide.c is broken for non ppc boards. The read/write functions does not add ATA base address, which causes failure. This patch solves that. It also contains a patch for shannon board that will be broken with this change. * Patch by Thomas Lange, 10 Oct 2003: fixes for ide on non ppc boards /Thomas diff -purN u-boot-0.4.8/common/cmd_ide.c u-boot-0.4.8_new/common/cmd_ide.c --- u-boot-0.4.8/common/cmd_ide.c 2003-07-01 23:07:07.000000000 +0200 +++ u-boot-0.4.8_new/common/cmd_ide.c 2003-10-09 00:06:50.000000000 +0200 @@ -42,8 +42,12 @@ #ifdef CONFIG_STATUS_LED # include <status_led.h> #endif -#ifdef __I386__ +#ifndef __PPC__ #include <asm/io.h> +#ifdef __MIPS__ +/* Macros depend on this variable */ +static unsigned long mips_io_port_base = 0; +#endif #endif #ifdef CONFIG_SHOW_BOOT_PROGRESS @@ -116,9 +120,8 @@ ulong ide_bus_offset[CFG_IDE_MAXBUS] = { #endif }; -#ifdef __PPC__ + #define ATA_CURR_BASE(dev) (CFG_ATA_BASE_ADDR+ide_bus_offset[IDE_BUS(dev)]) -#endif #ifndef CONFIG_AMIGAONEG3SE static int ide_bus_ok[CFG_IDE_MAXBUS]; @@ -763,7 +766,7 @@ ide_outb(int dev, int port, unsigned cha static void __inline__ ide_outb(int dev, int port, unsigned char val) { - outb(val, port); + outb(val, ATA_CURR_BASE(dev)+port); } #endif /* __PPC__ */ @@ -785,7 +788,7 @@ ide_inb(int dev, int port) static unsigned char __inline__ ide_inb(int dev, int port) { - return inb(port); + return inb(ATA_CURR_BASE(dev)+port); } #endif /* __PPC__ */ @@ -846,7 +849,7 @@ output_data(int dev, ulong *sect_buf, in static void output_data(int dev, ulong *sect_buf, int words) { - outsw(ATA_DATA_REG, sect_buf, words<<1); + outsw(ATA_CURR_BASE(dev)+ATA_DATA_REG, sect_buf, words<<1); } #endif /* __PPC__ */ @@ -870,7 +873,7 @@ input_data(int dev, ulong *sect_buf, int static void input_data(int dev, ulong *sect_buf, int words) { - insw(ATA_DATA_REG, sect_buf, words << 1); + insw(ATA_CURR_BASE(dev)+ATA_DATA_REG, sect_buf, words << 1); } #endif /* __PPC__ */ @@ -1420,14 +1423,14 @@ input_data_shorts(int dev, ushort *sect_ static void output_data_shorts(int dev, ushort *sect_buf, int shorts) { - outsw(ATA_DATA_REG, sect_buf, shorts); + outsw(ATA_CURR_BASE(dev)+ATA_DATA_REG, sect_buf, shorts); } static void input_data_shorts(int dev, ushort *sect_buf, int shorts) { - insw(ATA_DATA_REG, sect_buf, shorts); + insw(ATA_CURR_BASE(dev)+ATA_DATA_REG, sect_buf, shorts); } #endif /* __PPC__ */ diff -purN u-boot-0.4.8/include/configs/shannon.h u-boot-0.4.8_new/include/configs/shannon.h --- u-boot-0.4.8/include/configs/shannon.h 2002-11-03 19:03:56.000000000 +0100 +++ u-boot-0.4.8_new/include/configs/shannon.h 2003-10-08 23:45:24.000000000 +0200 @@ -204,13 +204,13 @@ #define CFG_ATA_BASE_ADDR CFG_PCMCIA_ATTRB_ADDR /* Offset for data I/O */ -#define CFG_ATA_DATA_OFFSET (CFG_ATA_BASE_ADDR) +#define CFG_ATA_DATA_OFFSET 0 /* Offset for normal register accesses */ -#define CFG_ATA_REG_OFFSET (CFG_ATA_BASE_ADDR) +#define CFG_ATA_REG_OFFSET 0 /* Offset for alternate registers */ -#define CFG_ATA_ALT_OFFSET (CFG_ATA_BASE_ADDR) +#define CFG_ATA_ALT_OFFSET 0 /*----------------------------------------------------------------------- */
