Linux distro on NSA325

[musv]

WarheadSE:

It seems, you have the full build environment installed. Can you please provide me a uImage with the that patch applied:

$this->bbcode_second_pass_code('', '#if defined(CONFIG_ZYXEL_NSA325)
/* MCU tries to reset CPU every 1 minute for avoiding system hang before watchdog timer is enabled.
* If watchdog timer is enabled, then set GPIO 14 to tell MCU that do not reset CPU.
*/
regValue = MV_REG_READ(0x1010);
regValue |= BIT14;
MV_REG_WRITE(0x10100, regValue);
#endif')

So I could at least do some first steps to play around and start learning on my Zyxel.

Erm, I don't think it's that simple... Both WarheadsSE and I have tried twiddling bits in those registers with the same result: device still reboots.

edit: BUT I might have missed (or forgotten) something: it reads from 0x1010 but writes to 0x10100.
does 0x1010 == 0x10100 ?

edit #2: I think I remember now. 0x1010 is read only and 0x10100 is write only. Maybe.

edit #3: I have tried flipping GPIO14 after a cold boot into Archlinux before. Device still rebooted.

I have done as necessary for both, in u-boot via memory modify (smacking the registers directly by address), and neither work there. I plan on bringing this into the kernel. This damned MCU is annoying..

It (the 325) is my next project, since someone was kind enough to donate a device specifically for me to bring up.

It's on my desk/bench at the moment.

Looking into getting a kernel patch together. Have to tear up their sources

[musv]

I'm currently installing a new kernel on my Gentoo machine and found this new option in the kernel config:

$this->bbcode_second_pass_quote('', 'R')eset Controller Support (RESET_CONTROLLER)

CONFIG_RESET_CONTROLLER:

Generic Reset Controller support.

This framework is designed to abstract reset handling of devices
via GPIOs or SoC-internal reset controller modules.

If unsure, say no.

Symbol: RESET_CONTROLLER [=n]
Type : boolean
Prompt: Reset Controller Support
Location:
-> Device Drivers
Defined at drivers/reset/Kconfig:4

Doesn't really look like anything useful... but then again, all of that stuff looks like gibberish to me

[WarheadsSE]

I have a feeling that uboot is protecting it some how, our the Ethernet linked mcu is in play.

Either way I test the kernel I've made tomorrow

Install instructions to come after testing

Does that mean it worked?

I'm sure he will give more details after he has tested.
