Could you provide a BOM for K230D Zero?
The schematics list TLV62569 used as DCDC buck converter, but TLV62569 has a max output of 2A and only a single one is used to convert to 0.8V - but at the same time the hardware design guidelines https://www.kendryte.com/k230/en/dev/00_hardware/K230_Hardware_Design_Guide.html list:
VDD0P8_CORE: 2250mA, recommended at least 3A DC/DC
VDD0P8_CPU: 1000mA, recommended at least 2A DC/DC
VDD0P8_KPU: 3000mA, recommended at least 4A DC/DC
How can a single TLV62569 be sufficient if the hardware design guidelines list ~6.25A @ 0.8V?
