Please check if the VDPA settings are appropriate for your board. In the source code the "External VDPA" is set, which is 0x00:

In this case your hardware must also be designed accordingly to support this mode. Wrong configuration of this setting may cause the lack of RF-Field.
 Please note, that PTX1xxR Config Tool discontinued support on configuring the VDPA setting, therefore a manual edit of the generated ptxNSC_RfConfigVal.c file is needed according to the following list of possible values:

"External VDPA": 0x00
"Adaptive VDPA": 0x10
"2.5V": 0x20
"2.75V": 0x30
"3.0V": 0x40
"3.25V": 0x50
"3.5V": 0x60
"3.75V": 0x70
"4.0V": 0x80
"4.2V": 0x90
"4.4V": 0xA0
"4.6V": 0xB0
"4.8V": 0xC0
"5.0V": 0xD0
"5.2V": 0xE0 


We strongly encourage our customers to use the "External VDPA" only to improve efficiency and performance. If you need other VDPA setting, please change it manually or use a simple one-liner shell command like:

sed -ie '/ptxNSC_RfConfig_RegsMisc/{N;s/\n(\s+0x)00/\110/}' SRC/COMPS/NSC/ptxNSC_RfConfigVal.c


Should you need the same change in a generated .dat file, please use a hex-editor like HxD to change the data at offset 0x296 accordingly:
