[U-Boot] warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules

I ran Software Update on my Fedora 13 system, and now whenever I build U-Boot, I get a bunch of warnings like this: dlmalloc.c: In function 'malloc': dlmalloc.c:2252: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2252: note: initialized from here dlmalloc.c:2261: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2261: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2261: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2261: note: initialized from here dlmalloc.c:2268: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2268: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2268: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2268: note: initialized from here dlmalloc.c:2325: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2325: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2325: warning: dereferencing pointer '({anonymous})' does break strict-aliasing rules dlmalloc.c:2325: note: initialized from here Can anyone explain why this is happening? I don't understand how a Fedora update would change anything, since my cross-compile toolchain is not distributed with Fedora, so it shouldn't have changed.

[U-Boot] [PATCH 2/4] cfi_flash: Add weak default for cfi_flash_bank_addr()
by Stefan Roese 01 Sep '10

01 Sep '10

cfi_flash_bank_addr(int bank_nr) returns the base addresses of the requested bank. Introducing this weak default enables boards to override this functions with a board specific version when required. This feature will be used in the lwmon5 board update, supporting runtime detection of 2 board revisions with different flash layouts.

[U-Boot] [PATCH 3/4] cfi_flash: Simplify dynamic flash bank number detection
by Stefan Roese 01 Sep '10

01 Sep '10

This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By moving these optional variables and defines into the common code, board specific code is minimized. Currently only the following board use this feature: APC405, IDS8247, TQM834x And IDS8247 doesn't seem to really need this feature, since its not updating the bank number variable at all. So this patch removes the definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port. This new framework will be used by the upcoming lwmon5 update as well.

Hi , I am trying to cross compile some libraries for ARM board I will port a Linux OS to the hawkboard. Want to study u-boot specific to this board so I ll be able to do this. The first chore is to port u-boot on this board. PLz help me , I was going through the uboot readme which directed me to straight away mail and share my concern. Thanks for the help Regards Vaishali

[U-Boot] "UnCorrectable RS-ECC Error" occurs when reading NAND flash under u-boot 2009.08 for i.mx25
by dajiang.zhong＠tektronix.com 01 Sep '10

01 Sep '10

Hi, every one. This is my first time of posting a message here, firstly , thanks for any body who builds such a nice platform give help. In recent two weeks, I added a NAND flash driver support for Micron's MT29F2G08ABD (SLC;page size: x8 2048+64bytes; Block size: 64 pages; Device size: 2Gb) memory chip base on u-boot 2009.08 for i.mx25. Block Erasing and Page Programming functions worked properly, but when I do page reading operation, "UnCorrectable RS-ECC Error" error message prompted. I checked the NFC (NAND Flash Controller) spare area buffer and found that the 4th 512-byte spare area buffer's data were very weird, there is not any ECC code that should be generated by the FEC but contained the data what I programmed to the memory. In order to easy to do troubleshooting works, I make a simply testing process, what I do is, firstly, I only erase page 0 of block 0, and later I program the erased page with a 2k file which consisted of 2048 same character 'E', at last I read the page back , but "UnCorrectable RS-ECC Error" occurs. I pasted the contents of NFC's spare area buffer as following: bb001000: ffffffff 66ffffff bab935d1 22446bbd .......f.5...kD" bb001010: b935d166 ffffffba ffffffff ffffffff f.5............. bb001020: 5f7467b9 21650de8 4d97fbd0 3166372c .gt_..e!...M,7f1 bb001030: 3b7e8bef b1cf62a5 bb8f50f6 de0031b3 ..~;.b...P...1.. bb001040: ffffffff 66ffffff bab935d1 22446bbd .......f.5...kD" bb001050: b935d166 ffffffba ffffffff ffffffff f.5............. bb001060: bafcf1fa 0c0698ef 09089d72 e6200c80 ........r..... . bb001070: d638f5ef 20130b40 591dd763 e224f527 ..8.@.. c..Y'.$. bb001080: ffffffff 66ffffff bab935d1 22446bbd .......f.5...kD" bb001090: b935d166 ffffffba ffffffff ffffffff f.5............. bb0010a0: 76fa88ba 7a648809 d27bbc43 6b2b81cf ...v..dzC.{...+k bb0010b0: f6b95e3b 1286638e 73d324fb 22880ce5 ;^...c...$.s..." bb0010c0: 45454545 45454545 45454545 45454545 EEEEEEEEEEEEEEEE bb0010d0: 45454545 45454545 45454545 45454545 EEEEEEEEEEEEEEEE bb0010e0: 36d8f3d5 0099a9e7 eb289d07 11664624 ...6......(.$Ff. bb0010f0: 4fbb9f24 505ab041 25ff61f6 43280406 $..OA.ZP.a.%..(C Contents written in red characters should be ECC code, but changed to what I programmed to the memory in preverious programming process. Any advice, please feel free to tell me. Thanks very much in advance. Thanks & Regards, Leon Zhong
