Part Number: AWR1243
1)I downloaded SWRA561A AWR1243 Bootloader Flow but found the paper seems to be about AWR1443
there is no cortex R4F in AWR 1243
and the DEV mode 011 (SOP mode 2) = Dev mode has not been mentioned at all
is there an accurate papers about AWR1243 Bootloader Flow ?
2) I have test VIN_13RF1/2 voltage is 1.3V and internal LDO (VOUT_PA VOUT_14APLL1) has no voltage output, isthat mean the RF part doesn't work at all ? BSS firmware has loaded
how can I get RF started?
thank you very much

5th step: SPI connect failed
the output Window shows :
10:10:43] [RadarAPI]: ar1.PowerOn(0, 1000, 0, 0)
[10:10:43] Status: Failed, Error Type: RESP TIMEOUT
some time SPI connect is OK but 6th step RF power-up failure
Status: Failed, Error Type: RESP TIMEOUT
SOP set as DEV mode(SOP =011) and I I use two separate 5V-2A DC power
What mistakes have I made here? How could I resolve these bugs?
And how can I get the DEV mode information ?
2，VIN_13RF1/2 voltage is 1.3V . This pin should be 1.0V ?but the schematic of AWR1243BOOST shows VIN_13RF1/2 connected to AR_1P3_RF1 which is 1.3V .

top side of your board and the markings on the IC。
I found it belongs to E2.0 mentioned in the document .
firmwares are from mmwave_studio_01_00_00_00/rf_eval_firmware/
