I2C NAK stopping SysTick

Question asked by hudson.ben on Jul 22, 2015
Hi there,

I'm trying to do a blocking I2C read in another interrupt. If I receive a NAK the HAL seems to crash (I'm seeing uwTick stop). Both the I2C interrupt and the interrupt I'm doing the read from have a lower (higher numerically) priority than the system tick timer.

Does anyone know why this could be happening?
