Hello Wolfgang Denk, It's my mistake to tag this observation as a bug. I will take care such thing does not repeat .
Could you *please clarify* couple of my queries* regarding posting questions* to the mailing list. + Most of the postings in the mailing list are observed to be code patches. Could we also post our observations/opinions on the code/commands/issues on a particular u-boot release and discuss with other u-boot contributors?? If yes, is there any specific string (similar to [PATCH] for a patch or a [BUG] for a bug etc) to be mentioned in the subject line?? I posted the below two queries earlier (first one yesterday and second one during last month) 1.[U-Boot] cmd: clarification on 'env ask' command execution 2.Unable to delete the hush shell local variables Both of them were not forwarded by the moderator (not sure what was wrong ). I re-sent the second query yesterday to the mailing list with subject line "*[U-Boot] [BUG] cmd : Local Hush Variable Could not be deleted* " and it got forwarded. So, any specific guidelines to post queries/observations/bugs for discussion will be definitely helpful and keep us going. + For newbies, could you suggest any pre-requisites, initial documents or guidelines to follow while they explore u-boot ( from user/tester/developer perspective ).
