Other Parts Discussed in Thread: UNIFLASH,

Dear All ,

we had developed a custom with AWR1843 . Some boards easily connect Uniflash and flashing happens .

Some board need multiple time power cycling to get flashing . My Questions is do we need pull reset line low for Uniflash to connect .

Regards

Aziz

    Hello,

    No, Uniflash does not need to reset the device. 

    It is possible that the SOP state is not being correctly latched when you power on the device. How is the NRST being controlled in your system? NRST needs to come high only after all of the supplies are stable and the SOP pins are stable at the expected voltage.
