one of them boots at around -8c and other around 0c. They work perfectly fine in room temp and NO they are NOT in recovery mode. As i said, we tested same software and same (our custom) carrier boards with MANY modules and modules from different shippment work ok OK. But this batch does not boot in 0c and -8c Tj PLL. 3 employees spend 3 weeks making sure its not our carrier board and not our software doing double blind experiments and we can 100% confirm its the modules from that batch fault. More than 2 modules from that shippment are acting the same. We either need a hotfix or replacements because they aren’t working as stated in the datasheet. We obviously tested power rails and power enable pins with scope and everything. Also always logged serial.
