Hi sir,
Now, customer designs his own schematic, he need to access the external device of 1443 through the JTAG interface for erasure and writing (5 pins JTAG and 1443 are directly connected, see JTAG. PNG).
How to realize it, thank you very much!
He referred to TIDEP-0091, but he wanna flash via JTAG port.

Thanks.
Hello Frank1,
For external JTAG connectivity you could use the XDS110 Debug Probe. It comes with various header options to JTAG connection.
Customer need to connect only TMS, TDI, TDO, TCLK and corresponding ground. Reset should not be connected, There is no RESET implemented in the JTAG connectivity to mmWave devices.

Please note below VIO caution notes in the data sheet , during the Boot/SOP configurations or Power cycling external JTAG should not be connected.
Only after the boot process JTAG need to be connected for the debug purpose.
Thanks and regards,
CHETHAN KUMAR Y.B.
