    Hi User,

    Can you provide more information on your custom board?

    Cheers,

    This circuit board was redesigned according to the official iwr1642 boost of ti. The circuit was exactly the same. TM4C1294NCPDTT3 chip was removed. Then I tested it with XDS110 through JTAG (One CTI-20 to Cortex-M 10-pin adaptor). SOP was set to 101. Then I found that flash could be formatted normally, but when downloading the program, it came out. Now the above error message.

    I tested the official iwr1642 boost, which normally appears as device information as soon as uniflash is running. But when my own 1642 circuit board runs uniflash, the startup interface appears the following information, which is displayed as 000000. The subsequent formatting is normal, and the download program will report errors.

    Thanks for your help!

    Supplement:

    1) TX and RX of 1642 on my own circuit board are not used. In 1642 boost, TX and RX are connected to TM4C1294NCPDTT3. Does this affect my download program?

    2) There is a question: if I use xds110 for development and debugging, do the JTAG and aux ports of xds110 need to be used? And make sure that the RX and TX of 1642 are connected to AUX in order to download the program?
