Follow-ups

--- Graf Yang 2009-04-29 00:50:57

I can't duplicate this bug.

I use toolchain 09r1 rc5, kernel 2009-04-26 rev 6307.

--- Mingquan Pan 2009-05-18 05:37:51

Yes, it is ok with trunk head kernel and toolchain 09r1 rc6 on board ADSP-BF548

Rev 0.2. Close it.

--- Mingquan Pan 2009-06-02 03:44:41

This issue shows up again in log from May 20.

It looks this is due to the u-boot updated to 09r1 from 08r1.5 that day,

because using the uImage prior May 20 to run on the same board with updated

u-boot also fails.

Maybe this bug should move to the u-boot bug tracker.

are you sure this isnt a dupe of [#4942] ? your tests there arent equivalent.

the first is u-boot in parallel flash while the second is in spi flash.

--- Mingquan Pan 2009-06-02 22:25:22

There should be two issues, because this kernel config CONFIG_PM is not set and

I try reboot with this kernel, it is ok.

The detailed config is attached.

You have not remove 'watchdog -f -s' from /etc/inittab

...

Have a lot of fun...

BusyBox v1.13.4 (2009-06-04 11:47:42 GMT) built-in shell (msh)

Enter 'help' for a list of built-in commands.

root:/> ps aux | grep watch

4 root 0 SW< [watchdog/0]

239 root 484 S /bin/watchdogd -f -s

root:/> kill -9 239

bfin-wdt: Unexpected close, not stopping watchdog!

root:/> ps aux | grep watch

4 root 0 SW< [watchdog/0]

243 root 484 S /bin/watchdogd -f -s

so you can't kill watchdogd, and the board will not reset.

It's not a bug.

Grace,

Sorry, now I duplicated this bug, boot nor flash fail, but spi flash is OK,

under debugging.

--- Graf Yang 2009-06-09 02:50:09

Fixed.

This intel nor flash chip is in status mode when watchdog reboot happen, this

cause nor flash boot fail.

Now it is put into array mode, after chip is unlocked.

None-intel chip will not do unlock operation in this case, so have not this

bug.

--- Mingquan Pan 2009-06-18 04:56:03

Yes, fixed. Close.
