[U-Boot-Users] ppc4xx relocate_code what it does????

Hi, After doing all the initializations (i.e) serail_init,init_baudrate etc.., finally it reaches to relocate_code(addr_sp,id,addr) in the board_init_f() function in the board.c file (lib_ppc\board.c) ppc4xx. what it does? which part of the code or data copies from flash to the ram? Is this required while I am running from the SDRAM? what part of the code I can skip in the relocate_code function? If running from the flash what should i do? Arun

[U-Boot-Users] Coldfire: Problem with linking / CFG_MONITOR_BASE

Dear List, I was trying to clean up my "new" mcf532x tree to prepare for sending patches, and switched back to CONFIG_MONITOR_IS_IN_RAM being undefined. Now, I get the following error during final linking: cpu/mcf532x/start.o(.text+0x452):start.S:163: relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text section in lib_m68k/libm68k.a(board.o) cpu/mcf532x/start.o(.text+0x504):start.S:266: relocation truncated to fit: R_68K_PC16 against symbol `int_handler' defined in .text section in lib_m68k/libm68k.a(interrupts.o) make: *** [u-boot] Error 1 I could track it down that this is triggered by the setting of #ifdef CONFIG_MONITOR_IS_IN_RAM #define CFG_MONITOR_BASE 0x40020000 #else #define CFG_MONITOR_BASE (CFG_FLASH_BASE + 0x400) #endif in my config.h, i.e. if I swap these two values, compilation fails in the other case. Can anybody give a hint what might be going wrong here? Thank you, Wolfgang

[U-Boot-Users] INTRUPT CONTROLLER FOR 405GP
by arun c 08 Aug '07

08 Aug '07

Hi all, I am working on a ppc405gp board. Whether uboot supports interrupt controller for 405gp? Did any one worked on ppc405 interrupt controller in u-boot?? Please tell me how to use the int contoller?? Best Regards, Arun

Re: [U-Boot-Users] [ARM] TI DaVinci support, 2nd attempt [0/5]
by Zach Sadecki 08 Aug '07

08 Aug '07

Sergey, You mentioned in a previous post that you had a serial boot utility you wrote to get away from the C# one that TI has... Did you write that in C? Could you share it with the list, since it would be most helpful to those of us who work with Davinci boards. Thanks for all your efforts with this port of u-boot. It will be great to be able to move up to a clean, well written version. I look forward to the NAND support especially, since the stuff in the TI supplied u-boot is almost 3 years old... Zach

[U-Boot-Users] Question about MIPS 4KE core
by Jun 08 Aug '07

08 Aug '07

Hi, all I am using U-boot 1.2.0, and intend to port it to a MIPS 4KE core cpu. From the hints in README, I read the source code in general. :) My Question is: would cpu/mips/*.s compatiable for a 4KE one? I have noticed that there is only a board for MIPS 4K, and some condition macro used in asm files. If I want to port succ, should I modify something in cpu/mips/*.s or only implement the source files in board/_MYBOARD_/ ? Thanks a lot. PS: Sorry for last message... -- I want to be an expert. I want to be a professional.
