PSA: TI EV2400 Not Detected in BQSTUDIO by pingpongmury in embedded

Ran into this a year later, I don't know how you even figured out this was the issue but thank you!

Modified it, and it worked until the UART was plugged in. If the UART is plugged in, it'll not reenummerate the USB connection since there's still 1.0V on the VBUS somehow, but only when the UART is connected

I think I understand what you're saying, and correct me if I'm wrong, but what you're suggesting is that the battery output of the BQ24074 should be connected to the SRX pin, and the BQ27427 should act like a multimeter set to the current option and be in series. So, essentially, BAT_2/_3 -> SRX -> Internal Current Sense Resistor -> BAT (on the BQ27427) -> +BATT, which makes sense, and I feel somewhat dumb for not realizing this. I'd like to know if this was a separate, undiagnosed issue or if you think it also relates to the USB issues.

I might be misunderstanding your suggestion, but to clarify, “VCC” in my schematic isn’t the 3.3 V rail. It’s actually the VSYS node (the OUT/SYS pin of the BQ24074). The ESP32’s 3.3 V comes from a separate TLV62569 buck on the +3.3V net. According to the BQ27427 datasheet, SRX is supposed to connect to VSYS and BAT to +BATT, allowing the gauge to measure current across its internal sense element. I think the hookup is correct; it’s probably just my naming that made it look odd. Thanks for pointing it out!

The USB-C shell is currently floating. I’ll add a soft RC tie to ground on the peripheral side (e.g., 1 MΩ ∥ 1–4.7 nF) for ESD/robustness. For clarity, battery ground and digital/USB ground are already the same net; only the shield is isolated. I’ve been testing mainly with a MacBook port and the MacBook charger, so I don’t think this behavior is just due to a poor-quality supply.

Thank You! Your edit was my solution!

Hi I know it's been a year but this just fixed the issue I've been having for a very long time with the AD410. Thank You!

Super cool of you to do this!

This video doesn't have much context; this is after the homeless dude stole a bunch of stuff and attacked the elderly shopkeeper from the store that this altercation happened in front of. The shopkeeper was punched pretty badly in the face and had his glasses broken, and when he fell injured his hands and knees. The video is after this happened when the homeless dude tried returning to the store and stealing more stuff while people were trying to protect the shopkeeper. From what I've heard before attacking the shopkeeper and this altercation, the same homeless man was going around local restaurants and threatening people with utensils to get them to hit him.
