Let me understand if I get this right. for example, I have a block of 8 words, starting at 0x0: 00000000: a b c d 00000010: e f g h where a is the crc32 computed on b,c,d,e,f,g,h Within uboot, I would like to compute the crc32 of b,c,d,e,f,g,h and compare it with a. -- Compute CRC and store at address 20 crc 1 7 20 -- Compare CRCs if itest *0 == *20; then echo CRC ok; else echo CRC bad; fi Is that correct? Thanks and best regards, FF

[U-Boot] [PATCH 00/28] Add link-local addressing support
by Joe Hershberger 30 May '12

30 May '12

Link-local support allows the bootloader to get a usable network address regardless of network environment. Given that bootloaders may not always have access to a DHCP server, this functionality makes accessing it in those environments easier. It is also referred to as zero-configuration IP. The following script allows the network to be configured for DHCP, link-local, and static IP addresses configurably by the environment using "dhcpenabled" and "linklocalenabled". #define CONFIG_EXTRA_ENV_SETTINGS \ "ipconfigcmd=if test \\\"$dhcpenabled\\\" -ne 0;" \ "then " \ "dhcpfail=0;dhcp || dhcpfail=1;" \ "else " \ "dhcpfail=-1;" \ "fi;" \ "if test \\\"$linklocalenabled\\\" -ne 0 -a " \ "\\\"$dhcpfail\\\" -ne 0;" \ "then " \ "linklocal;" \ "llfail=0;" \ "else " \ "llfail=-1;" \ "fi;" \ "if test \\\"$llfail\\\" -ne 0 -a " \ "\\\"$dhcpfail\\\" -ne 0; " \ "then " \ "setenv ipaddr $sipaddr; " \ "setenv netmask $snetmask; " \ "setenv gatewayip $sgatewayip; " \ "fi;\0" \ Some refactoring of net/ was done to make adding link-local support cleaner as well as generally improving the readability and organization of the code. Tested on da850_am18xxevm Tested on MPC8313ERDB_33 check-patch No warnings or errors (depends on ignoring CONSIDER_KSTRTO) MAKEALL -a powerpc No additional warnings or errors beyond master MAKEALL -a arm No additional warnings or errors beyond master git-test-sequence Cleanly bisectable Code-size affects on MPC8313ERDB_33 shown below > cat sizeofMCP8313 make BUILD_DIR=/tmp/u-boot-build/ ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- USE_PRIVATE_LIBGG=yes distclean > /dev/null && \ make BUILD_DIR=/tmp/u-boot-build/ ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- MPC8313ERDB_33_config > /dev/null && \ make BUILD_DIR=/tmp/u-boot-build/ ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- USE_PRIVATE_LIBGG=yes > /dev/null && \ powerpc-linux-gnu-size /tmp/u-boot-build/u-boot > git-test-sequence origin/master..
