Hi all, I have upgraded the Letux kernel to 4.7-rc1.
For the first time an -rc1 merge went through smoothly without the need to resolve any conflicts.
There were only 3 minor fixes when rebasing our feature branches on top of it.
Of course there are still bugs [1]. Some introduced by automatically changed config or others because some APIs might have been changed that are used in our (still) private additions.
Here is the result:

Some interesting changes I did see (without further analyses and no guarantee for completeness) * there is a BMC150_I2C driver now * it looks as if we can set a led-trigger to "panic" which could help for debugging
BR, Nikolaus

Hi,
thanks for the information!
Maybe this could help finding the issue why our prototype crashes when using 1,5GHz on the core.
This is my last main concern we should try to find the reason for before setting up the mass production.

Of course there are still bugs [1]. Some introduced by automatically changed config or others because some APIs might have been changed that are used in our (still) private additions.

Some interesting changes I did see (without further analyses and no guarantee for completeness)
- there is a BMC150_I2C driver now
- it looks as if we can set a led-trigger to "panic" which could help
for debugging

Yes, that is my hope as well.
and omapconf might also help to find out if there are subtle differences in the DSS with our two different ssd driver architectures.

Hi all, I have upgraded the Letux kernel to 4.7-rc1.
For the first time an -rc1 merge went through smoothly without the need to resolve any conflicts.
There were only 3 minor fixes when rebasing our feature branches on top of it.
Of course there are still bugs [1]. Some introduced by automatically changed config or others because some APIs might have been changed that are used in our (still) private additions.
Here is the result:
http://git.goldelico.com/?p=gta04-kernel.git;a=shortlog;h=refs/heads/letux-4...
Some interesting changes I did see (without further analyses and no guarantee for completeness)
- there is a BMC150_I2C driver now
- it looks as if we can set a led-trigger to "panic" which could help for debugging

I am not sure since it works on the stone age old Openmoko-Beagle-Hybrid (Beagle XM + Openmoko display) which also has a tca for some fancy LEDs.
But you might still be right, since there is no pwrseq on that board.
I have seen another unexpected bug:
[ 453.668121] Division by zero in kernel. [ 453.672180] CPU: 0 PID: 941 Comm: irq/237-tsc2007 Not tainted 4.7.0-rc1-letux+ #353 [ 453.680206] Hardware name: Generic OMAP36xx (Flattened Device Tree) [ 453.686798] [<c010f180>] (unwind_backtrace) from [<c010b6d8>] (show_stack+0x10/0x14) [ 453.694946] [<c010b6d8>] (show_stack) from [<c03ec930>] (dump_stack+0x98/0xd0) [ 453.702514] [<c03ec930>] (dump_stack) from [<c03eb3e4>] (Ldiv0+0x8/0x14) [ 453.709564] [<c03eb3e4>] (Ldiv0) from [<bf09f538>] (tsc2007_soft_irq+0x274/0x3b0 [tsc2007]) [ 453.718353] [<bf09f538>] (tsc2007_soft_irq [tsc2007]) from [<c018ee3c>] (irq_thread_fn+0x1c/0x34) [ 453.727630] [<c018ee3c>] (irq_thread_fn) from [<c018f0d4>] (irq_thread+0xec/0x1c8) [ 453.735595] [<c018f0d4>] (irq_thread) from [<c015175c>] (kthread+0xd8/0xec) [ 453.742889] [<c015175c>] (kthread) from [<c01070d0>] (ret_from_fork+0x14/0x24)
So at the moment the status is: * OMAP5EVM: seems to work * Pyra: seems to work * PandaBoard: seems to work * GTA04: kernel panic * BeagleBoard XM + Panel: div0 error from touch screen
Untested: * BeagleBone + Panel * OpenPandora
In general this is quite good for a -rc1.
