[U-Boot-Users] AT91RM9200 Bits...
by Joe Grisso 23 Sep '05

23 Sep '05

Hello all, I was wondering who was working on the AT91RM9200 bits within the U-Boot CVS tree? I'm currently bringing up a new hardware platform and see where pieces could be streamlined. Some with code changes to the lowlevel_init.S file, and some with just simple variable changes. Going over the register init routine I found 3 registers that are written to (MC_PUIA, MC_PUP, MC_PUER) that are shown as reserved on the RM9200 datasheet and errata. Also, there's a definition to the SMC2_CSR which the atmel datasheet shows as SMC_CSR0. Bringing a lot of these #defines and whatnot in line with the datasheet would help folks that are new to U-Boot porting navigate everything easier. :-) Best Regards, Joe Grisso Detachment 3 Media, Ltd.

[U-Boot-Users] [PATCH] mips lds alignment bug
by Geoff Cleary 23 Sep '05

23 Sep '05

The following patch corrects a problem in (at least) the dbau1x0/u-boot.lds The bug only shows if the GOT requires alignment onto 16 byte boundary. In this case the _gp symbol is aligned, but the actual GOT section is not. *** u-boot_fix/board/dbau1x00/u-boot.lds 2005-09-23 13:38:13.126887305 -0400 --- u-boot/board/dbau1x00/u-boot.lds 2005-09-23 13:38:32.392077670 -0400 *************** *** 46,53 **** . = ALIGN(4); .sdata : { *(.sdata) } ! . = ALIGN(16); ! _gp = .; __got_start = .; .got : { *(.got) } --- 46,52 ---- . = ALIGN(4); .sdata : { *(.sdata) } ! _gp = ALIGN(16); __got_start = .; .got : { *(.got) } Geoff

Hi All, I need to know how to configure 8MB Flash on PPC405ep board. I already have 4MB flash on PPC405ep board working fine . I am using u-boot as my bootloader. Can anybody tell me what are the registers to be configured at Processor side(i am new to this register settings) or memory controller side. Please tell me the steps that i need to follow to write my own dirver(i may take existing driver as reference). Thanks in Advance, --Nagi

[U-Boot-Users] vmlinux kernel image(IN ELF BINARY format) for making uImage
by Swapnil Ashok Narkhede 21 Sep '05

21 Sep '05

Hi, I have several doubts. 1>> The README of U-boot says for generating uImage we have to get vmlinux image in ELF BINARY FORMAT. How do i know if the vmlinuz image that i have is in ELF BINARY format? 2>> I have a vmlinux image compiled from MontaVista Linux for COnsumer Edition. The size of this image is 28 MB but when i use this image in generating uImage the linux.bin that is genrated is of 1.7MB and after gzipping it and finally making uImage the uImage is of 775Kb. How is this possible? What is exactly happening out here? Is it a right way to pass MontaVista Kernel image to Uimage? Why is there so much of reduction in size? Please help me clear this concept Regards, Swapnil Narkhede Mob:- 0432025023 Email:- s3092131(a)student.rmit.edu.au School of Computer Science and Information Technology RMIT University, Melbourne

[U-Boot-Users] [PATCH] computation of framebuffer palette for 8bpp lcd bitmaps
by Francesco Mandracci 21 Sep '05

21 Sep '05

-- This patch is a bug fix. -- Description on the bug: using 8 bits/pixel framebuffer, all (splashscreen) bitmaps with palette colors whose RGB components differ in the 5 high bits in the blue byte and/or in the 6 high bits in the green byte do not display correctly. -- How my patch fixes this bug: computing correctly the palette entries. The C code fills a 16bit palette entry with 3 RGB bytes in the form RRRR RGGG GGGB BBBB [....|....|....|....] masks: (R,G,B) (0xf800, 0x07e0, 0x001f) fedc ba98 7654 3210 The used bits are the highest 5 bits for the red and blue bytes and the 6 high bits for the green byte. This did not change neither in PowerPC nor in PXA in all cvs.sf.net revisions I've found. The computation may be either: colreg = ((red & 0xf8) << 8) /* [RRRR|Rrrr|....|....] */ | ((green & 0xfc) << 3) /* [....|.GGG|GGGg|g...] */ | ((blue & 0xf8) >> 3); /* [....|....|...B|BBBB]bbb. */ or: colreg = ((red << 8) & 0xf800) | ((green << 3) & 0x07e0) /* versus " << 4" */ | ((blue >> 3) & 0x001f); /* versus " >> 0" */ I choose the latter form because it's the way you adopted. -- A way of demonstrating that the patch actually fixes something is simply displaying such a bitmap (either splashscreen or simply as argument to "bmp display"). For instance obtaining a 640x480 8 bpp bitmap from http://www.dreamvideo.it/video/immagini/monoscopio.jpg: the original code displays greys as yellowish and blues as rubbish, while the patched code displays everything correctly. -- (no new features) -- CHANGELOG entry * Corrected the computation of framebuffer palette for 8bpp lcd bitmaps Patch by Francesco Mandracci, 16 Sep 2005 -- CREDITS entry N: Francesco Mandracci E: francesco.mandracci(a)primaelectronics.com P: ID=0xF6B25635 P: Fingerprint=4059 B2F9 E987 105D 00C8 3DEA 848C F56A F6B2 5635 D: Hacking PXA270 -- (no new board) -- (no new configuration options) -- The patch itself: ------------------------------------------------------------------- Index: common/lcd.c =================================================================== RCS file: /cvsroot/u-boot/u-boot/common/lcd.c,v retrieving revision 1.5 diff -p -u -r1.5 lcd.c --- common/lcd.c 4 Jul 2005 00:03:16 -0000 1.5 +++ common/lcd.c 16 Sep 2005 13:07:00 -0000 @@ -638,8 +638,8 @@ int lcd_display_bitmap(ulong bmp_image, bmp_color_table_entry_t cte = bmp->color_table[i]; ushort colreg = ( ((cte.red) << 8) & 0xf800) | - ( ((cte.green) << 4) & 0x07e0) | - ( (cte.blue) & 0x001f) ; + ( ((cte.green) << 3) & 0x07e0) | + ( ((cte.blue) >> 3) & 0x001f) ; #ifdef CFG_INVERT_COLORS *cmap = 0xffff - colreg; ------------------------------------------------------------------- -- (single file) -- (single modification) -- ok for all boards -- modifications are at the minimum -- thinking that the memory footprint is affected in a reasonably way -- in order to respect the 40Kb size limit I'm not sending the very bitmap file Ciao Francesco Mandracci

[U-Boot-Users] A question about the raminit in u-boot
by FCG WANG Baohua 21 Sep '05

21 Sep '05

Dear All: I have a question about the u-boot: I use a 128M board, the u-boot is OK, but when I changed the same config board, except the ram changed to 256M, it crashed when going into relocate_code() in board.c, and not going into board_init_r(), I had changed in mpc8260ADS.c initdram(), from 128 to 256, and changed the BR2 registers in mpc8260ADS.h. What's the other need to be changed? thanks!
