IWRL1432BOOST: Subject: Inquiry Regarding "Schematics/PROC140B(002_IWR)_Sch.PDF" Circuit Diagram

JAEHOON KIM
Intellectual 405 points
Part Number: IWRL1432BOOST
Other Parts Discussed in Thread: UNIFLASH, AWRL1432

Tool/software:

Dear TI support Team,

I am preparing to design a board similar to the IWRL1432BOOST using the "Schematics/PROC140B(002_IWR)_Sch.PDF" circuit diagram, and I have a few questions:

I would like to upload firmware to the IWRL1432BGAMFQ1 on my custom-designed board. Can I switch the board to Flashing Mode and use the Uniflash program to write the firmware? If not, could you please provide the additional steps required to accomplish this?

On page 8 of the "Schematics/PROC140B(002_IWR)_Sch.PDF" circuit diagram, there are CURRENT SENSORS and a TEMPERATURE SENSOR. Can these sensors be left unconnected (NC), or are the sensor values essential for operation, meaning the system relies on their readings for proper functionality?

I look forward to your guidance on these matters.

Best regards,

    Hi there,

    You can program the device by loading the binary (appimage) in the QSPI flash and you can use Uniflash in device's flashing mode for this. To understand the bootloader flow please refer to the application note:

    https://www.ti.com/lit/ug/swru622a/swru622a.pdf 

    The current sensors and temperature sensors are for development purpose. These components could be left in the custom board. The current sensors are to estimate the overall power consumption on the respective rails, and the temperature sensor is for temperature calibration purpose.

    You can also take a look at our reference designs:

    AWRL1432 KTO reference design: https://www.ti.com/tool/TIDEP-01036 

    IWRL6432FCCSP reference design (60GHz): https://www.ti.com/tool/TIDEP-01030 

    Thanks,

    => I understand the previous explanation. Thank you for your response.

    However, I still have some questions:

    When using a custom board with the TI TM4C1294NCPDT-128 (XDS110) IC, is it necessary to write firmware to the IC? Or, similar to the TI IWRL1432BOOST board, can I simply use Uniflash to write the appimage file without any additional setup?​

    Hi,

    Yes, with XDS110 you can simply upload the binary (appimage) using uniflash in device's flashing mode to the QSPI flash memory and run the application in functional mode. No additional requirements are there. The QSPI Flash memory is required for this. I hope you are using this in your design.

    In flashing mode, the device RS232 lines will help loading the binary to the external QSPI Flash memory. In functional mode the binary will be loaded to the device ROM from the external memory.

    If you do not have external QSPI Flash memory, please refer to the appnote:
