Other Parts Discussed in Thread: SYSCONFIG, UNIFLASH
I am using Ubuntu 18.04 and attempting to connect to the AM243x launch pad. I have a usb-c adapter that is spec'd for 5V @ 3A. The launch pad is fresh out of the box and unused previously.
When I try to plug in the usb-c cable to supply power the red LED stays lit and I never see any green LEDs turn on. I have tried switching to a different 5V, 3A adapter and still have not had any luck. The documentation I read stated that I should be getting 3 green LEDs to turn on and the red one to only blink once and stay off. I'm assuming this is the root of my issues. Maybe I have a bad out of the box dev board?
I think the power problem may be the root of my issue, but just in case here is what I have done so far.
I am following the setup found in the AM243x MCU+ SDK 08.01.00. I have gone through the "Getting Started" documentation to get set up. This includes going through the "Download, Install and Setup SDK and Tools" and "Download, Install and Setup CCS". I have installed each dependency that was required for Ubuntu that is shown at all steps. I have verified that I see sysconfig 1.10 and the TI CLANG v1.3 under products and compilers of code composer studio respectfully.
The issue occurs when trying to follow the steps for "EVM Setup". I have tried setting the switches to 01000100 as instructed in the documentation and then powering back on. Then running
sudo python3 uart_uniflash.py -p /dev/ttyACM0 --cfg=sbl_prebuilt/am243x-lp/default_sbl_null.cfg
from the mcu+ sdk directory under tools/boot.
This just hangs and never uploads anything.
I then went to the out of box quick start to use the cloud tools (https://dev.ti.com/gallery/view/SitaraMCU/AM243x_LaunchPad_OOB_Experience/ver/1.0.4/). Step 3 of the quick start immediately fails when trying to setup the serial connection. I get an error stating no response from the chip and to unplug and re-plug in the USB.
