[U-Boot-Users] Activating hush shell

[Andreas Engel]

Hi,

I'm trying to switch from the old shell to hush on a custom ARM board
with u-boot 1.1.2 by just defining CFG_HUSH_PARSER and
CFG_PROMPT_HUSH_PS2 in the config file. However, u-boot now doesn't
really wait for user input, but endlessly prints its console prompt.
Before digging deeper into the problem with a debugger: do I need to do
anything else beyond just enabling hush?

No, this is basicly  all.  But  don't  forget  that  the  syntax  for
variable  substitution  changes.  If  you  have any "preboot" command
definitions that refer to variables this might cause trouble.

Best regards,

I didn't forget it, thanks. Meanwhile, I found out that the hush shell
doesn't like the bootretry feature (at least on my board). Disabling it
made the shell work, but that's not a solution in the long term.
