Ok will check the MangoH board voltages and get back for any questions.
As for the msm_sdcc, in the link : All wifi commands failing with Mirage board,
The tiwifi script was modified to incorporate msm_sdcc, disable the i2cset values.
Followed the same as in link.
If the msm_sdcc is intended for mangoH Green board, then i would probably skip it.
Please confirm.
