Other Parts Discussed in Thread: CC3220SF, UNIFLASH
After some months I'm back again on a project based on CC3220SF. First, with the LP I can use both JTAG and serial (Uniflash).
Then I have my own custom board, already tested a couple of months ago. The only difference is I had to clean my PC and reinstall all again. Hence I guess my issue is related to some configuration.
The problem is Uniflash cannot connect to my board: it says timeout reading data or sometimes timeout while waiting ack.
I did the following:
- removed all jumpers from the LP
- connected the rx/tx from XDS (the two pins above the headers) to my board
- connected gnd, reset and also the JTAG pins (in fact I can debug my application)
- the SOP pins are: pull-down, pull-up, pull-down
To be sure I tried to swap the tx/rx lines.
What do you suggest to dig deeper in this issue?
