Part Number:TPS65986
Hi, Team
My customer project using our TPS65986 act as the USB+DP to C dongle(adapter) for the PC. the dongle(adapter) is to display the DP signal to the Type-C monitor using ALT mode.
Normally, the dongle(adapter) is in DFP and the monitor is in UFP. but customer found that if the monitor in DFP and the dongle(adapter) in UFP, the TPS65986 can not enter ALT success. pls check the attach file for more detail information.
BTW, customer using our TUSB546 EVM binary file to program the flash directly(see the bin file in attachment), so they didn’t have the project file.
And I also post the issue in e2e before(https://e2e.ti.com/support/interface/f/138/t/720275), BU share the TUSB546EVM project file to us, and help us change some configuration(add DR_SWAP function) base on the TUSB546EVM project file.
But after check, all these 2 project file can not work. Also pls also notice that customer using the TUSB546EVM BIN file for projection, this BIN file size is 1M, but the new BIN file just 135K. so we think the new project file is not the same as former project file. Could u help to check and give some comments?
Thanks.
