The timeout for i2c is tiny, and might be dependent on optimisation level.

bl602-hal/src/i2c.rs

Lines 163 to 168 in dfa6556

    
               /// Set the timeout when waiting for fifo (rx and tx). 
        
               /// It's not a time unit but the number of cycles to wait. 
        
               /// This defaults to 2048 
        
               pub fn set_timeout(&mut self, timeout: u16) { 
        
                   self.timeout = timeout; 
        
               }

we should switch to using mcycle and sysclk to wait for a few hundred microseconds instead.
