[U-Boot-Users] WARNING: in ext2fs.c
by Roberts, John 30 Sep '05

30 Sep '05

In function: ext2fs_read_file(ext2fs_node_t node, int pos, unsigned int len, char *buf) You may not be getting all the bytes you requested in the 'len' parameter. Your requested length might be improperly adjusted. ----------------------- Code snippet ------------- unsigned int filesize = node->inode.size; /* Adjust len so it we can't read past the end of the file. */ if (len > filesize) { len = filesize; } ----------------------------------------------------------- "len" is the native requested size, while "filesize" is the files real size, but byte-swapped and the two are being compared. As long as the byte-swapped length value is larger than the requested size value, then you'll never have a problem. Now assume the file is 2meg and you requested 2meg. IF( len=200000 (2meg) > filesize=2000(2meg byte-swapped) ) THEN len = filesize You end up getting only 2000 bytes. The initialization of filesize should be: unsigned int filesize = __le32_to_cpu (node->inode.size); Not: unsigned int filesize = node->inode.size; (440gx) -John Roberts

> Will you please just read the manual? Sorry, maybe I searched in the wrong place I read here: http://www.denx.de/twiki/bin/view/DULG/Manual and in detail here: http://www.denx.de/twiki/bin/view/DULG/LinuxInFlash where you say "Below is a transcript of the complete operation with a final iminfo command to check the newly placed Linux kernel image in the flash memory." But there is not example about howto store images in flash. Could you please point me in the right direction ? TIA

Using AT91rm9200DK and u-boot 1.1.3 I wonder how can I store uImage and ramdisk into flash memory avoiding to load them from tftp server each time. Could someone provide me a simple example of u-boot commands and parameters or a link ? TIA

[U-Boot-Users] [PATCH] Update OMAP242x for git head (plus sign).
by Woodruff, Richard 29 Sep '05

29 Sep '05

Hello Wolfgang, Attached is a patch generated today from a pull from the u-boot.git tree using cg-mkpatch. Please apply this and dump any patches you might have in your queue. Your updates over the weekend left the omap242x processor on head non-functional. This patch is completely 24xx contained. I have stopped using drivers/cfi_flash.c and moved to using a private board copy as discussed in an earlier thread. The couple of files external touches are just changing from CONFG_OMAP2420 to CONFIG_OMAP24XX. * Patch by Richard Woodruff, 28 Sep 2005: OMAP242x H4 board update - Switch to private cfi_flah.c file. - Make work for 2422 mono-ddr. - Make work for 2420-POP. - Use clock gauging to determine crystal speed. - Fix warm reset problem with bad OTGCTRL access. - Switch to DDR unlock mode operation for DLL errata. - Remove obsolete APTIX conditionals. - Display more information at startup. - Use 24XX instead of 2420 in prep for future chips.
