Troubleshooting can be continued with ST_CDSP_RF_SUPPLY_TEST VINKU flowchart because there
are errors with eight VINKU error codes.
Typically this kind of error occurs if there is no VBAT_ASIC voltage coming to the Vinku TX ASIC at
all or the ASIC is poorly soldered to the PWB (All voltages that are somehow related to VBAT_ASIC
are causing errors).
