Umm... but you don't have to change anything to acchieve this. That's already what we have now. U-Boot never does anythingonit's own - it only performs the commands you give it. If you do not send a command to U-Boot to perform a TFTP download it will not do anything - it will just wait for your commands. > So in this kind of systems we may have TFTP server in u-boot. This makes absolutely no sense to me. You are wasting your efforts here. If you want to be able to control U-Boot remotely, then just do it - either obver the serial console interface, or using netconsole over Ethernet. This is actually much more flexible than the solution you have in mind - and you don;t have to spendany efforts on it because it's all already available. > Please let me know if this is clear.

[U-Boot] [PATCH] mpc85xx shrink boot block page to 1M

[U-Boot] Installing Linux kernel, nothing to execute in RAM...

Hi! I have a modifed MPC8360 platform with a U-boot git-version from October. Now I'm trying to install a Linux kernel and everything looks fine until it starts to execute the kernel in RAM, there is only some bad assembler instructions and then a lot of Invalid Opcode. If I look at the log_buf there is nothing interesting there. bootm fc010000 - fc008000 ## Booting kernel from Legacy Image at fc010000 ...

[U-Boot] [PATCH v3] i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functions
by Timur Tabi 17 Dec '08

17 Dec '08

All implementations of the functions i2c_reg_read() and i2c_reg_write() are identical. We can save space and simplify the code by converting these functions into inlines and putting them in i2c.h. Signed-off-by: Timur Tabi <timur(a)freescale.com> --- v3: add 8xx-specific code, and include PRINTDs from blackfin and pxa I'm posting this patch because I'm enhancing the I2C routines to support multiple I2C busses more easily, but I need to clean up the existing code first. I'm going to be on vacation when the next merge window opens, so I'm posting this now in the hopes that it will be picked up when the window does open. cpu/arm920t/at91rm9200/i2c.c | 14 --------- cpu/arm926ejs/davinci/i2c.c | 17 ----------- cpu/blackfin/i2c.c | 16 ---------- cpu/mpc512x/i2c.c | 17 ----------- cpu/mpc5xxx/i2c.c | 16 ---------- cpu/mpc8220/i2c.c | 16 ---------- cpu/mpc824x/drivers/i2c/i2c.c | 14 --------- cpu/mpc8260/i2c.c | 16 ---------- cpu/mpc8xx/i2c.c | 33 --------------------- cpu/ppc4xx/i2c.c | 20 ------------- cpu/pxa/i2c.c | 15 ---------- drivers/i2c/fsl_i2c.c | 16 ---------- drivers/i2c/soft_i2c.c | 19 ------------ include/i2c.h | 62 +++++++++++++++++++++++++++++++++++++++- 14 files changed, 60 insertions(+), 231 deletions(-) diff --git a/cpu/arm920t/at91rm9200/i2c.c b/cpu/arm920t/at91rm9200/i2c.c index b68c5dd..9fd72d3 100644 --- a/cpu/arm920t/at91rm9200/i2c.c +++ b/cpu/arm920t/at91rm9200/i2c.c @@ -189,20 +189,6 @@ i2c_init(int speed, int slaveaddr) return;

[U-Boot] li r0,__got2_entries@sectoff@l
by youhello youhello 17 Dec '08

17 Dec '08

hi all: i am a u-boot beginner, i found a line code "li r0,__got2_entries@sectoff@l" in almost all mpc start.s.i have tried to delete sectoff and i got same result of uboot with "li r0,__got2_entries@l". could you tell me what difference between "li r0,__got2_entries@sectoff@l" and "li r0,__got2_entries@l" and why the author use "li r0,__got2_entries@sectoff@l" but not "li r0,__got2_entries@l".thanks very much.

[U-Boot] v2009.01-rc1 is out - update of release schedule
by Wolfgang Denk 17 Dec '08

17 Dec '08

Hi everybody... first the good news: v2009.01-rc1 has just been released. Not the not so good news: as you can see from the release name we have shifted the schedule by nearly a full month. There were several reasons for doing so: - We are (actually: I am) late with merging all the patches that have been submitted for this release. - The remaining time would not allow for thorough testing, especially since most people are not available because of Christmas vacation. - Shifting the release date allows us to get re-synced with the LInux release cycle, i. e. we try to avoid an overlap of the Linux and the U-Boot merge windows. Thus, the new planned release date is January 17, 2009. Sorry for the delay... Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de On the subject of C program indentation: "In My Egotistical Opinion, most people's C programs should be indented six feet downward and covered with dirt." - Blair P.

[U-Boot] [PATCH] IXP425: Improving print_cpuinfo code Part 1/1
by Stefan Althoefer 17 Dec '08

17 Dec '08

[PATCH] IXP425: Improving print_cpuinfo code The existing version of print_cpuinfo did read the processor ID and detects clock speed from this. This is not correct, as the IXP425 has the ability to "downgrade" clock speed by using strapping resistors. The improved code reads strapping information from register and corrects the actual clock speed. Both information are displayed. The patch is against "latest" u-boot git-repository Please (still) be patient if style of submission or patches are offending.
