Re: Re: [microblaze-uclinux] keyboard

[sashti srinivasan <svasn_rtems@xxxxxxxxx>]

Hello,

   Thanks for your informations.  Without being clear
about Microblaze's terminologies and conventions, I
assume that base and high addresses specify the memory
mapped address ranges for peripheral devices.  Here
are a few statements(and questions) in continuation:

(1)  You have obtained the PS2 controller from
opencores.  The problem is, your driver does not
receive the scancodes.  Are you sure that PS2
controller is getting the scancodes correctly?

(2)  Is the PS2 controller verified in isolation? 
That is, we can direct the outputs of controller to
seven segment display so that each time there is a
key-press some symbol is displayed on the 7SD.  The
symbol is uniquely correlated with the key pressed. 
Scancodes are available on the WWW and can be verified
with the display.  Probably something similar is
already done.  Is it?

(3)  I guess that you have written the keyboard
driver.  Please provide more information about it if
possible.

(4)  Please give me the complete URL of the PS2
controller you have obtained.

(5)  Provide more details about your PS2 controller
and driver.

(6)  Can anyone tell me whether any instruction set
simulator available for Microblaze wherein, one can
boot uCLinux and have display of the sash prompt.  I
asked about this here roughly a year ago when
microblaze-uCLinux was just blossoming.  It was not
available at that time.  Is anyone trying it?  Or is
it available now?

Thanks
Srinivasan
