[ECOS] RedBoot RAM version problem

[Andre Sebastien <sebastien dot andre at sxb dot bsf dot alcatel dot fr>]

Hi everyone;


I build a Redboot RAM version for a ARM7TDMI PID Board.
Download it into RAM via t32 software + lauterbach; JTAG link
And i Run IT

The start output of Redboot :


+FLASH: driver init failed!, status: 0xd

RedBoot(tm) bootstrap and debug environment - built 16:17:25, Jul 26 2001

Platform: PID (ARM 7TDMI)
Copyright (C) 2000, 2001, Red Hat, Inc.

RAM: 0x00000000-0x00080000, 0x0001a0f8-0x00080000 available
RedBoot>

SO i see that Redboot can t initialize the FLASH DRIVER !!
===> + FLASH: driver init failed!, status: Oxd

So when i try to make a fis init command the system HANG when he try to print the
message: ... Warning:device contents not erased, some blocks may not be usable...

At this moment i had think that FLASH package wasn t added to redboot
Then i had try an ecosconfig add flash but .... it has already into redboot
configuration.

So now i think that i have some problem with JUMPER of my board !!
in a ecos documentation  i see that i need to put it:

SET JUMPER 7-8 on LK6 (using the angle cpde in the 16 bit EPROM)
SET JUMPER 5-6 on LK6 (select 8bit ROM mode)
SET JUMPER LK18 (ROM REMAP - this is also required for ecos)
SET S1 to 0-0-1-1

So when i did it after i can run the hello example in ram !!!
What i shloud do ?
My working configuration for run in ram is :
JUMPER 7-8 on LK6   ON
JUMPER 5-6 on LK6   OFF
JUMPER LK18 OFF
S1 is to 1-1-1-1

thanks for your help.

best regards,
Sebastien.
