Fail to fastboot

Hi everyone

I’m working with inforce6301 module.
I am using this module with my custom board.

When I fastboot to the inforce6301, I got the following log and fail to fastboot.

target reported max download size of 268435456 bytes
sending 'boot' (11488 KB)...
OKAY [  0.364s]
writing 'boot'...
FAILED (remote: Warning: battery's capacity is very low
)
finished. total time: 0.370s

My custom board does not have battery. It works with AC cable.
What does this log mean ?

And is there a way to avoid this problem ?

Please help me.
Thank you.

I think you probably need to discuss that with Inforce support. I don’t recall ever seeing that on a Drabonboard.

Thank you for your response.
I will contact to inforce.

Thank you.

The reason is the value of Vcc for my custom board.
The minimum battery voltage defined in boot loader is 3.6V but my custom board Vcc is 3.5V.

#define BATTERY_MIN_VOLTAGE 3600000 //uv

I changed the above value to 3400000 and fastboot works well.

Thank you.
