AWR1843: Connection with AWR1843 and TM4C129ENCZAD

Part Number: AWR1843
Other Parts Discussed in Thread: TM4C129ENCZAD, , TM4C129ENCPDT

Hello, I want to use TM4C129ENCZAD to allow my computer and AWR1843 to communicate.
(TM4C129ENCPDT is out of stock everywhere.)

I use the early TM4C as a conversion adapter by preparing as in the thread below.

e2e.ti.com/.../tm4c129enczad-what-you-need-to- install-xds110firmware-on-tm4c129enczadt3-on-the-hardware-side/4212353#4212353

I said

Hardware:
USB Connector
JTAG Connector
XDS110-Debbuger

SW:
Bootloader.bin
xdsdfu command

Next, we must follow the step to install DFU to TM4C129ENCZADT3.

1. Install 'bootloader.bin' to TM4C129ENCZADT3 with JTAG Protocol.

2. Do the xdsdfu Command which you tell me the step .

By the way, I paste the figure, My idea is OK?

Is it possible to set the initial settings as above?
Also, can it be used as a conversion adapter even if it is changed to ENCPDT?

    Hello,

    If you have the TivaC MCU then you should not need to use the external XDS110 debugger. You can connect to the JTAG through CCS using the TivaC via the USB, so the external XDS110 debugger is redundant and can be removed.

    Can you please check with the ARM MCU E2E forum to make sure that the same firmware will work for both TM4C129ENCPDT and TM4C129ENCZAD? We have not tested this MCU on our radar, so you need to confirm with the MCU team that the same firmware and pin utilization is possible, otherwise, you would need to create your own firmware which could be difficult if you do not have experience with this. It is very important to verify this before you design a board with a new MCU, based on the datasheet it seems like both parts have the same serial interfaces so it should work, but you should confirm this first with the MCU team.

    Assuming it does work with the existing firmware, then the steps for programming would be the exact same as mentioned to you in the other thread.

    OK.
    Let's check it again on the MCU thread.
