Hi,

We think we have similar problem to this ticket: https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/945572/dlpc3479-pattern_ready-signal-is-not-going-back-from-low-to-high-in-dlpc3479  and this ticket:
https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1174906/dlpc3478-the-dlp-oven-has-an-outage-problem/4440031?tisearch=e2e-sitesearch&keymatch=dlpc3478#4440031 

Those threads mention new firmware, which is in validation phase. Would it be possible to get access to the pre-release firmware and test in our system.  We see our problem randomly around 1 out of 200k sequences,  so it takes a bit of time to reproduce. symptoms are similar to those threads above, either pattern ready doesn't go to ready-state, or the dlpc3478 simply doesn't start the pattern sequence after sending i2c start command.
