Some questions about Redboot

Altera_Forum · ‎10-05-2005

I use Cyclone 1c20 development board and ecos 5.0

Here below the redboot message indicates FLASH:0x80000000 but my flash is at 0x0000000.

Is it normal and in relation with bit 31 to disable the cache memory ?

********

RedBoot bootstrap and debug environment [ROMRAM]

Non-certified release, version UNKNOWN - built 14:20:59, Oct 4 2005

RAM: 0x01000020-0x02000000, [0x0102d51c-0x01fec000] available

FLASH: 0x80000000 - 0x80800000, 128 blocks of 0x00010000 bytes each.

== Executing boot script in 10.000 seconds - enter ^C to abort

RedBoot> fis load myelf

RedBoot> go

********

The boot script timeout is 10sec but I have less time to enter Ctrl C 2 or 3 seconds only.

I would like to know if FIS in redboot is compatible with a filesystem in eCos, my goal is to read some parameters in the Redboot config in the FIS directory from my eCos application and may be to create a customer Redboot config in ram which could be read by redboot to do an automatic application update.

This solution seems not too difficult to put in place, but need some modifications in Redboot to switch from default config to customer config.

May be someone has tested this or other solution to update application in the field.

In eCos mailing list some speak about an EXPECT script to automate the update. Is there anybody who knows which langage it is?

Thanks for advices.
