Ok, I see.
But tps65217C (in BBB) has a more power availability vs. tps65217B (in BBW).
Reducing the CPU speed is not the solution. For example I would like to
work with a clock speed of 1GHz.
So, are You suggesting that the PMIC is incorrect?
Can anyone else give an opinion? Maybe the designers

I confirm that I have the same issue with a BBB A5B using TI 3.2 kernel.
After reading the full thread I guess that the posible workarounds are:
- Using Angstrom 3.8 kernel.
- Powering the BBB from USB.
- Limiting the CPU frequency.
Can anybody confirm it?
