Forum Post: ADC frozen, ADC_STAT.FSM_BUSY set

Hi,

We have a LINUX application that uses TSC ADC in continuous mode. It works

correctly but freezes after a few minutes / hours. We do not have any explanation

yet, but it is reproduced if we force the ADC pin down to the ground.

When we kill and restart the application that reinitializes the ADC, we see that the

ADC FSM_BUSY is equal to 1. No acquisition is done, and the fifo count is 0.

We have to reboot the system for the ADC to work again.

The frequency divider register is set to 0 (divider = 1).

Do you have any explanation or workaround ?

Thanks for your support,

Fabien Le Mentec.
