Device invariably "dies" after some time

[marctrem]

Dear Tamago authors,

I cannot get the device to live further than a minute on tamago.
The issue has been reproduced with tamago-go#1.18.1 and tamaga-go#1.18.3 and the latest tamago.
The bootloader is loaded using SDP.
Since I lack the debugging hardware, it's rather hard to figure the root cause. No panic is emitted.
The issue is observed with and without the sd card being inserted.

Repro

Code

func init() {
	model := imx6.Model()
	if !imx6.Native {
		banner += fmt.Sprintf(" - %s %d MHz (emulated)", model, imx6.ARMFreq()/1000000)
		return
	}
	if err := imx6.SetARMFreq(900); err != nil {
		log.Printf("WARNING: error setting ARM frequency: %v", err)
	}
}

func main() {
	select {}
}

Steps

1. Plug the device
2. Flash through SDP
3. Blue led goes from soft to hard
4. Wait ~34s
5. Blue led goes from hard to soft -- device is unresponsive

Please let me know if I can help with that investigation.

Thank you!

May I see your imports?

Does tamago-example result in the same?

Please note that you must import the usbarmory board package for watchdog initialization and that blocking functions which are not executed in a new goroutine, while no other goroutine is running, will cause a deadlock.
