2011-03-21UBI: Fix error code handling in ubi commandsStefan Roese
Some ubi commands returned negative error codes, resulting in the following error message on the prompt: "exit not allowed from main input shell." Negative error codes are not allowed. This patch now changes the UBI code to return positive error codes. Additionally "better" error codes are used, for example "ENOMEM" when no memory is available for the UBI volume creation any more. Also the output of some commands is enhanced: Before: => ubi read 100000 testvol 100000 Volume testvol found at volume id 0 read 1048576 bytes from volume 0 to 100000(buf address) => ubi write 100000 testvol 1000 Volume testvol found at volume id 0 After: => ubi read 100000 testvol 100000 Read 1048576 bytes from volume testvol to 00100000 => ubi write 100000 testvol 1000 4096 bytes written to volume testvol Signed-off-by: Stefan Roese <sr@denx.de> Cc: Wolfgang Denk <wd@denx.de>
2010-12-03UBI/UBIFS: Automatically unmount UBIFS volume upon UBI partition changeStefan Roese
Automatically unmount UBIFS partition when user changes the UBI device. Otherwise the following UBIFS commands will crash. Signed-off-by: Stefan Roese <sr@denx.de>
2010-08-08various cmd_* files: fixed layout a little bitFrans Meulenbroeks
Most of the files have U_BOOT_CMD on a separate line, but a few didn't and had the first line on the same line as U_BOOT_CMD. This changes these files by adding a line break and a tab Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com>
2010-07-24cmd_usage(): simplify return code handlingWolfgang Denk
Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too. Signed-off-by: Wolfgang Denk <wd@denx.de>
2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

2010-04-09cmd_ubi: Fix uninitialized variable warningPeter Tyser
gcc 3.4.6 previously reported the following error on many MIPS boards which utilize UBI: cmd_ubi.c:193: warning: 'vol' might be used uninitialized in this function The current code is structured such that 'vol' will never be used when it is NULL anyway, but gcc isn't smart enough to figure this out.

2009-07-09Handle VID header offset in ubi part commandSimon Kagstrom
The VID header offset is sometimes needed to initialize the UBI partition. This patch adds it (optionally) to the command line for the ubi part command.

2009-06-12General help message cleanupWolfgang Denk
Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

2009-04-27ubi: Remove flash selection parameter (nor|nand|onenand) from "ubi part"Stefan Roese
This patch removes the now unnecessary flash type parameter from the "ubi part" command. Currently the user has to define the type of flash he will be using UBI on. Example: => ubi part nor partition1 With this patch this type parameter is not needed anymore. The user can now select the partition directly without the flash type paramter. Example: => ubi part partition1 This breaks backward compatibility right now because of the change in the command syntax. But UBI support is still quite fresh and the advantage of this new command is syntax big enough for this change. Additionally the code is much cleaner now.

2009-04-04UBI/cfi-mtd: Fix mtd name for multiple chipsAndreas Huber
On platforms with multiple NOR chips, currently only the first one can be selected using the "ubi part" command. This patch fixes this problem by using different names for the NOR "mtd devices". It also changes the name of the NOR MTD device from "cfi-mtd" to "norX" (X indexing the device numer) to better match the mtdparts defaults.

2008-12-10UBI: Set ubi_dev.type back to DEV_TYPE_NONE upon failing initializationStefan Roese
With this patch we set the type back to NONE upon failing UBI partition initialization. Otherwise further calls to the UBI subsystem would try to really access the non-existing UBI partition. Thanks to Michael Lawnick for pointing this out. Signed-off-by: Stefan Roese <sr@denx.de>

2008-11-24UBI: Change parsing of size in commands to default to hexStefan Roese
Currently the size parameters of the UBI commands (e.g. "ubi write") are decoded as decimal instead of hex as default. This patch now interprets all these values consistantly as hex, as all other standard U-Boot commands do. Signed-off-by: Stefan Roese <sr@denx.de>
