hi, in case you are having problem with LASER_NEN (always high), then you can try the following step, it solved my problem regarding LASER_NEN

- in manual, Power Up section
... Step 7 "Enable laser by setting Forced_Disable bit (bit-0) of LASER_CTRL0 register (address 0x20) to 0"

after SROM download, instead of writing 0x00 to addr 0x20, try writing 0x80 to addr 0x20
