I am working with linux-omap-2.6 v2.6.28-omap1 tag. I enabled the TWL4030 MADC and TWL4030 BCI drivers. I passed interrupt details to these drivers from platform_device structure from my board file. I could get the AC charging working. The AC and USB detection worked. However the USB charging is not happening. I read through the TPS TRM and took the dumps of the registers from BCI and some from TWL USB module and BOOT_BCI whenever I plug in the USB charger between host and the board. The register settings seem to be fine. But the battery is not charging. I am using BQ27000 chip for battery monitoring and I can see the battery voltage is decreasing. =46ollowing are the register dumps of TWL with and without USB plugged = in: These are the register contents when USB charger is plugged in: BCIMDEN =3D 0x11 REG_BOOT_BCI =3D 0x37 REG_POWER_CTRL =3D 0x20 REG_BCIMFSTS4 =3D 0xf4 REG_BCIMFSTS1 =3D 0x13 REG_BCIIREF1 =3D 0x68 REG_BCIIREF2 =3D 0x3 REG_BCIMFEN4 =3D 0x6f REG_BCIMFSTS2 =3D 0x0 REG_BCIMSTATEC =3D 0x12 REG_STS_HW_CONDITIONS=3D 0x90 These are the register contents when USB charger is plugged out: BCIMDEN =3D 0x0 REG_BOOT_BCI =3D 0x35 REG_POWER_CTRL =3D 0x20 REG_BCIMFSTS4 =3D 0xf0 REG_BCIMFSTS1 =3D 0xaa REG_BCIIREF1 =3D 0x68 REG_BCIIREF2 =3D 0x3 REG_BCIMFEN4 =3D 0x68 REG_BCIMFSTS2 =3D 0x0 REG_BCIMSTATEC =3D0x0 REG_STS_HW_CONDITIONS=3D 0x10 Is there anything more I need to support to get BCI USB charging working? Need I follow any USB Communication protocol between Host and the board. I have pasted the kernel boot logs for reference at the end. Can any one please guide me to some pointers? --=20 Best Regards Pramod Starting kernel ...
