emac resetting error, esp32 crashing..

[engrziarehman]

i am using esp32 and lan8720 module perfectly with arduino code but now i have shifted to mongoose os, as i have created blank code using mos init command, and added library only.
- origin: https://github.com/mongoose-os-libs/ethernet
now when i set eth.phy_addr=1 and eth.enable=true using rpc following messages are on console appearing:

I (4530) emac: emac resetting ....[0m[0;32mI (4530) emac: emac resetting ....[0m[0;32mI (4540) emac: emac resetting ....[0m[0;32mI (4540) emac: emac resetting ....[0m[0;32mI (4550) emac: emac resetting ....[0m[0;32mI (4550) emac: emac resetting ....[0m[0;32mI (4550) emac: emac resetting ....[0m[0;32mI (4560) emac: emac resetting ....[0m[0;32mI (4560) emac: emac resetting ....[0m[0;32mI (4570) emac: emac resetting ....[0m[0;32mI (4570) emac: emac resetting ....[0m[0;32mI (4570) emac: emac resetting ....[0m[0;32mI (4580) emac: emac resetting ....[0m[0;32mI (4580) emac: emac resetting ....[0m[0;32mI (4590) emac

after a while esp32 crashes and sometimes reflashing is required.
