Hello,
We used a simple RC circuit for our reset circuit of XEF216-512-TQ128 to wait 1ms after the power is enabled. Sadly, our chip only boots if we start a program with the XTAG Programmer, but it is our goal to make it start if powered on. I attached screenshots of our boot sequence below (Yellow=Reset_N, Blue=3,3V, Red=1V). Do you think we have a hardware problem here, or is there a special flag in the software that is needed to start the XMOS processor when it is powered on?
Thank you in advance; we appreciate any helpful information!

Simpler RC isnt good for XMOS plus at moment of reset you need valid CLK. Not scoped.
Try quicker RC or better voltage controller reset ICs.

See the section headed "Board Integration" in the data sheet.
