DLPC3478: HOST_IRQ OF DLPC3478 is always high

Other Parts Discussed in Thread: DLP3010LC, , DLPA2005

Tool/software:

Hello,

May I ask the DLPC3478+D3010LC+DLPA2005 combination, in which DLPA2005 does not use VLED function (about VLED-related pin suspension processing), and uses other chips to power the LED of the optical module separately? I use FWSel_DLPC3478_DLPA2005_pm1_i2c0x36_v9p2p0.img to flash of DLPC3478, it  can not successfully start DLP3010LC, and HOST_IRQ OF DLPC3478 is always high, what is the reason?
