S32K388 Phy init stuck in LWIP example

[chansookang]

Hello,

I am trying the "baremetal lwip s32k388" by using S32K388-EVB-Q289. Rev B

I want to use GMAC0 instead of  GMAC1. So i change the configs to GMAC0. 

But when debugging, i stuck in phy init() in while loop (establish link)

I cant find any information( ex. data sheet) about TJA1120, so i dont know how to test lwip ping by using GMAC0

Hello @chansookang ,

What version of S32K3's RTD do you use?

Please check that jumper J361 is closed:
