[U-Boot-Users] Wrong compiler called for as flags
by Robert Schwebel 08 Jul '04

08 Jul '04

Hi, while trying to make u-boot gcc-3.4 compilable I just found a strange effect. The attached patch tries to fix the issues that came up on the list during the last days. As gcc-2.95.3 is not able to generate code with -march=armv5 -mtune=xscale, I tried to make the decision on compile time by finding out which compiler we have. This basically works, but for the compilation of cpu/pxa/start.S it looks like the host compiler is taken instead of the cross-gcc to determine the compiler flags. You can easily reproduce this by applying my patch and compiling with a 2.95.3 cross gcc, then grepping the output for 'armv5'. The incorrect results come from the fact that, in this case, CROSS_COMPILE is not set, so instead of arm-linux-gcc the host gcc is called to determine the test. My assumption is that the effect comes from the order the different Makefiles and config.mk files are included when being called from cpu/pxa. Unfortunately this is not easy to debug - maybe there is somebody with better Makefile debugging skills than me on the list ;) Robert -- Dipl.-Ing.

Hello! All: Does u boot can support muti-cell memory (NAND Flash & SDRAM) (Samsung MCP KAG00E007M ). Should I re-write the code for it or use the which reference code? http://www.samsung.com/Products/Semiconductor/MCP/NAND_based/KAG00E007M/ds_k ag00e007m_18v_x16_107_105x13_06.pdf Thanks, Best Regards, Sammy

[U-Boot-Users] A question of tftpboot

Hello, I am using tftpboot to download the uImage. But I found if I use tftpboot 10000 uImage The image can be downloaded with no problem. But if I use tftpboot 1000 uImage Then it shows me execeptions as below: ******************************************************************** => tftp 1000 uImage-uncomp ENET Speed is 100 Mbps - HALF duplex connection TFTP from server 138.31.3.162; our IP address is 138.31.3.77 Filename 'uImage-uncomp'.

[U-Boot-Users] More 8540/8560 ADS Patches Soon
by Jon Loeliger 07 Jul '04

07 Jul '04

Wolfgang, I have some more development for the 8540/8560 ADS boards that I would like to turn into patches and submit to the list. However, I'd like to make those patches versus the top of CVS after my previous set have been applied if possible. Do you have a feel for when you might be able to get to them? Just FYI, the new development here will incorporate support for larger (up to 2G) memories on the 8540/60 ADS boards, and will incorporate some changes from Tom Armistead sent privately to me. Thanks, jdl

Hello, I built my design with EDK (using BSB base system builder) I generated my xparameters.h I compiled U-boot I generate an ace file. ($ xmd genace.tcl -jprog -board ml300 -hw implementation/download.bit -elf u-boot -ace top.ace, I used: genace.tcl given by xilinx in a reference design) When running u-boot on the ML300 board, I have nothing on Hyperterminal??? I don't understand where is the problem Thanks Abdelmajid

RE: [U-Boot-Users] [PATCH] ARM720t -- Relocating Exception Vectors

No offense, but this is a bad hack. The copy code belongs from a 'structured' point of view to where the relocation is done and not just attached to the end of the source code. And from an 'optimized code' point of view it belongs there, too, as _TEXT_BASE is already loaded there into an register for example, no need to do this multiple times. I don't quite see the necessarity for a loop, too. There are 7 exception vectors, never more, never less. The copy procedure can be handled by a single ldmia/stmia pair. Best regards, Lars Friedrich --
