[U-Boot-Users] [Q]changing serial baudrate in linuxppc_2_4_devel...
by 장형욱 04 Nov '03

04 Nov '03

I ported u-boot-0.4.0 and linuxppc_2_4_devel(from denx) to the custom board (PPC405GPr core) and it worked fine in serial baudrate 9600.... Now I'm trying to set baudrate to 115200 in u-boot and pass it in board information structure(bi_baudrate) to linux kernel... I followed the source of linuxppc_2_4_devel from head_4xx.S to start_kernel() but I couldn't find any parts in the kernel to use baudrate from u-boot bd_info setting. Isn't it the way it works ?? so I changed /etc/inittab in root file system as follows... console::respawn:/sbin/getty console 115200 and modified kernel console_init(void) <-- drivers/char/tty_io.c { /* Setup the default TTY line discipline. */ memset(ldiscs, 0, sizeof(ldiscs)); (void) tty_register_ldisc(N_TTY, &tty_ldisc_N_TTY); /* * Set up the standard termios. Individual tty drivers may * deviate from this; this is used as a template. */ memset(&tty_std_termios, 0, sizeof(struct termios)); memcpy(tty_std_termios.c_cc, INIT_C_CC, NCCS); tty_std_termios.c_iflag = ICRNL | IXON; tty_std_termios.c_oflag = OPOST | ONLCR; tty_std_termios.c_cflag = B38400 | CS8 | CREAD | HUPCL; tty_std_termios.c_lflag = ISIG | ICANON | ECHO | ECHOE | ECHOK | ECHOCTL | ECHOKE | IEXTEN; /* modified by hwjang */ tty_std_termios.c_ispeed = B115200; tty_std_termios.c_ospeed = B115200; ... } and login prompt comes out fine but linux booting message before login prompt doen't come.... could you tell me how to set baudrate of kernel by passing it from u-boot or by modifiyng kernel source itself or by changing menuconfig option ?? here is the minicom messages...

[U-Boot-Users] scc3 on MPC862
by somshekar chandrashekar kadam 04 Nov '03

04 Nov '03

Hi , On my custom board clk2 and clk4 of SCC1 used for transmit txcs and receive rxds , i have changed the port pin configuration from SCC1 to SCC3 , I am confused with SICR register setting , on SCC1 value set is 0x0000003d which means brg1 and CLK4 AND CLK2 for Rcx and TCx are set correct if I am wrong ? on my scc3 port can I use the same clock routing ,when i am not using SCC1. ? now I have to use SCC3 in Uboot its mentioned use brg3 then what will be the clock settings , ihave no idea ,? how do confirm this ? Thanks In Advance Neelu

RE: [U-Boot-Users] [PATCH-1/2] LAN91C111
by Woodruff, Richard 03 Nov '03

03 Nov '03

Hi Stephen, Yes I suppose. When I snoop packets I have gotten what I expected. Could be luck I suppose, I'll check the address block we use. The reset of the changes looked reasonable....switching the one word access to a byte access might need looking at...I seem to recall reading threads where some boards weren't wired up to do 8 byte accesses correctly. I'd cross check with the kernel level driver 91c1111 or 91c9x.c, before making that change. Might be ok.

Hi Richard It is not a problem of hard coded mac addresses because smc_mac_addr[] will be used as buffer storage too. Furthermore it's a problem of type casting from signed char to unsigned short (type of word) when writing the mac address into LAN91C111 (near line smc91111.c:smc_open():700 the USE_32_BIT branch). Note: it could be _only_ a NIOS related problem, but I think the type unsigned char for smc_mac_addr[] is more exact in common case, or not?

I've been using the 91111 for a while now. I've not had any real problems with it. As the environment I'm in has some 30 odd boards, I've never used the hard coded mac address.

There is (just was :-) a fat signed/unsigned bug in drivers/smc91111.c which is significant at NIOS plattforms when you are using MAC addresses with address elements above 0x7f.

[U-Boot-Users] Help with u-boot 0.4.0 and IBM ASH board
by Wetterlind, Eric 03 Nov '03

03 Nov '03

Good afternoon... I have an IBM ASH (NPe405h) board that I am trying to get U-Boot 0.4.0 running on. Ultimately, I'll port this over to our custom board that is very similar to the ASH, but I figured it would be better to start on a known platform. I downloaded the new 0.4.0 U-Boot and ran these two commands (after modifying the Makefile to run 'ppc_405-' instead of 'ppc_8xx'): make ASH405_config make all It flew through compile and link to produce the nice u-boot.srec. I put that in my tftpboot directory, telnet'd over to the abatron 2000, erased ASH flash and programmed this new image in there. The result is an immediate SystemError LED illumination. I then switched from Flash to SRAM (one of the dips on the ASH board) and reloaded. Running from SRAM produces a program exception and jump to 0x700 almost right off the bat. I am running out of ideas on how to get U-boot and my ash board to cooperate. Has anyone else that has tried this had the same problems? Regards, Eric (eric.wetterlind(a)goodrich.com)

[U-Boot-Users] ocdemon for initial u-boot flashing?
by Richard Klingler 02 Nov '03

02 Nov '03

Good evening.. Small off-topic question (o; Someone using OCDemon flash programmer for initial flashing of u-boot to a 8260 board? Installed the demo version and it keeps saying that it can't run target code...or is unable to write to RAM location... Was only once able to erase an existing old firmware...but that's all. Seems it needs some more initialisation than those offered in the software... Wrote a simple jtag flash program for Linux/Windows to do JTAG flashing but it takes some time for programming though (o; thanx for any hints rick

[U-Boot-Users] SCC3 ethrnet port on PMC862
by somshekar chandrashekar kadam 01 Nov '03

01 Nov '03

Hi, I am new to U-boot, please say if i am wrong , on my custom board i am using mpc862 and using scc1 as my ethrnet port its works fine, i have scc3 for ethernet also, in linux kernel i changed the configuraton file to change to use scc3 , i see nothing happening, is it because in uboot i have enbaled scc1 and enabling scc3 in linux kernel so not working ? i dont think this should be the problem as linux kernel resets the CPM, i am must be able to use scc3 on linux, any ideas please throw some light . anyone has enabled scc3 on uboot for mpc862 , i dont find any code reference , what things i need to change , ? Thanks IN Advance Somshekar

[U-Boot-Users] about the system clock config
by wang cheng 01 Nov '03

01 Nov '03

Dear Wolfgang Denk: I have configed my WindRiver mdppro8xx board according to the TQM8xxL module.The outcome is : ________________ U-Boot 0.4.8 (Oct 31 2003 - 15:47:15) gd->cpu_clk=25000000 immr=0xff002101 pvr=0x500000 CPU: XPC823xxZTnnB2 at 25 MHz: 2 kB I-Cache 1 kB D-Cache Board: WindRiver mdppro8xx DRAM: 16 MB before relocate_code() ---------------- Now I want to set my system clock to 50MHz. In the TQM8XXL.h there are clauses like these: __________________ "#if defined(CONFIG_80MHz) ..... #elif defined(CONFIG_66MHz) ........ #else /* 50 MHz */ ........." ------------------ so I added these:#define CONFIG_80/66/50MHz,but the outcome are still : ________________ CPU: XPC823xxZTnnB2 at 25 MHz: 2 kB I-Cache 1 kB D-Cache ---------------- Why did my #define CONFIG_80/66/50MHz not work? The gd->cpu_clk is evaluated in cpu/mpc8xx/speed.c by gd->cpu_clk = measure_gclk();but the function measure_gclk() seems have nothing to do with my board.h,right? So where to modify my system clock to 50MHz?:-) I have a vxWorks BSP of my WindRiver MDP8xx pro board.Everything is OK in vxWorks enviroment,now I want to run linux on it so the first thing is to port u-boot to it.I have modified the system_clock registers like SCCR/PLPRCR according to the romINIT.s in vxworks bsp,but there are nothing outcome in the hyperteminal.

[U-Boot-Users] where to modify my system clock in a tqm8xxl model?
by wang cheng 01 Nov '03

01 Nov '03

hello,all Congratulations on the release of the u-boot-1.0.0!Can you tell me where to set the system clock in a tqm8xxl model? My hyperteminal has displayed this (there are some "printf" added): U-Boot 0.4.8 (Oct 31 2003 - 15:47:15) gd->cpu_clk=25000000 immr=0xff002101 pvr=0x500000 CPU: XPC823xxZTnnB2 at 25 MHz: 2 kB I-Cache 1 kB D-Cache Board: WindRiver mdppro8xx DRAM: 16 MB before relocate_code() Now I want to set my system clock to 50MHz,but I don't know how to modify,which file should I modify?I know the gd->cpu_clk is initialized in cpu/mpc8xx/speed.c. Thank you for your time!
