micflash keeps hanging

Jun_Hyun_S_ · ‎03-06-2014

Hi,

I've been struggling with MPSS installation for some time now.

I started out in Ubuntu cross-compiling, but then gave up for obvious reasons. (didn't seem worth the trouble)

I installed CentOS 6.4 minimally, and started building necessary stack from ground-up, finally installing MPSS 3.1.4.

After I finished I mistakenly issued command for C0 stepping (micflash without -smcbootloader option)

I knew it was a mistake because /sys/class/mic/mic0/stepping has 'B1' in it.

It obviously failed, and I found a similar case on Developer Zone

I tried the procedure offered there. (power-cycle, put mic in ready state, micflash with -smcbootloader)

Even though I tried multiple times, (I even updated BIOS version because it was the issue in some cases I found here)

I couldn't get it to work.

4G decoding and spread spectrum in the BIOS is enabled and disabled, respectively.

Whenever I use micflash command with -v (and sometimes it finds the valid images),

The images go from 9%, 19%, 28%, and then it keeps writing 0% until it times out.

What should I do now?

(I attached the tarball produced by micdebug.sh)

Okay, this is my progress since I posted this.

I didn't realize that while I was 'yum update'ing from the minimal CentOS 6.4,

I unintentionally updated it to 6.5, which called for a kernel version that fit 6.5.

I took care of that.

Now micflash finds valid images every time I power cycle, but still, it times out.

I gave it a -v option to see its progress. Here goes:

No image path specified - Searching: /usr/share/mpss/flash

mic0: Updating SMC: 77%
mic0: Updating SMC: 86%
mic0: Updating SMC: 0%
mic0: Updating SMC: 0%
... and it goes on like this.

This is actually after my first power cycle. First time I tried micflash it went on to update SMC boot-loader, Flash, and hung while updating SMC.

I will keep on going at it until I get some feedback,

but meanwhile, I'm attaching a copy of the new debug log, reflecting the changes I made so far.

I finally got it to boot!

micflash worked after the second power cycle.

Its booting timed out after third, but it didn't after fourth!
