Hi Wulf, I am using the custom built kernel image in my own board where the TPS65217 driver is not required as it is not battery driven.
The BBB supports an option to battery backup. It also supports going to sleep mode, and wake-on events to wake up the CPU based on the RTC, The TPS65217 supports power saving by lowering the core voltage. I don't need this, as it allows some hardware simplification and flexibility if I don't use this features. Ignoring the TPS65217 will allow me to change the hardware independent of the software. The way to disabling the TPS65217 may be in the void am33xx_spl_board_init(void) routine that is in the board.c file. But I am not sure how to do it. Could I get know how to do it. If I could get the image loaded in BBB with TPS65217 driver removed then it should work for my custom board.
