Would it make sense to send 4 and 5 separately , so the fixes can land faster? Also, could you please try and avoid the SCU dependency on patch 7 , and more in that direction , can the PRG be made a bit more optional, so the iMX95 can still be supported by the DC driver ? -- Best regards, Marek Vasut
