Hello:
We have a 66ak2h12 demo board from ti
Recently, we found u-boot can't work well, when boot up, u-boot error that "No ethernet found."
I also use xtcievmk2x.gel and xds200 to connect the board .but it also error: Timeout pd=2, md=7! Timeout pd=2, md=7!
in .gel file
// Modules on power domain 2
#define LPSC_PA (7)
#define LPSC_SGMII (8)
Tt seems that power domain 2, Modules 7 and 8 don't work well.
In u-boot cmdline,
md.l 0x02350128 1
resul is:
0x00000040
It means that transition never clear and never completes. so the gel file error: time out
Because this board works well last week, and till this week , we doesn't do anything.
We don't know what to try next. Why power domain 2 's transition never clear when power on?
Please help!
