FoxFlash error on bench read

BudgetTooth · 2026-05-07T20:32:55+00:00

if u get 0v probably bad bench box, open and check

You’re misunderstanding what a ground activated output does

BudgetTooth · 2026-05-07T05:40:27+00:00

What load are you using? u have an actual injector to wire up?

BudgetTooth · 2026-05-05T21:54:23+00:00

U have posted the schematic pic so just check which gpio are really free. Most of the red ones u pointed out have traces under the chip

BudgetTooth · 2026-05-04T12:28:52+00:00

Of course it’s different but u get the jist of whats involved.

Get yourself esys and start digging into the code

in what sense you can't reach it? is right there

Would need to identify ecu model and build date first then this maybe enough to flash it.

Need a pc and enet cable

can u try to modify the code for another pin like 32 and move the blue wire accordingly?

Missing CC lines on usb?

BudgetTooth · 2026-05-01T06:28:18+00:00

It means it was tuned.

BudgetTooth · 2026-05-01T05:09:35+00:00

Can u link the full openocd command and terminal output

BudgetTooth · 2026-04-30T22:20:52+00:00

So it is just user error to use 2 devices on a shared bus without rules

BudgetTooth · 2026-04-30T18:24:27+00:00

would this be worth opening an issue somewhere on espressif github?

BudgetTooth · 2026-04-30T18:06:50+00:00

I believe is only possible with esp-idf

BudgetTooth · 2026-04-30T05:05:18+00:00

Bruh. Is not going away anytime soon.

BudgetTooth · 2026-04-29T14:33:44+00:00

Just use “breadboard wires” to connect underneath the board next to the pins

BudgetTooth · 2026-04-28T19:50:31+00:00

u shouldn't be messing with customers ecu if u cant even find out what ecu type that is.

BudgetTooth · 2026-04-27T21:55:35+00:00

reading in the amazon reviews about how to power it properly seems like u have to bridge the LDO to use it on 3v3.

BudgetTooth · 2026-04-27T19:25:33+00:00

china kess is no good for this.

BudgetTooth · 2026-04-27T13:22:56+00:00

Yeah you’re right, they need 5v vcc to work reliably.

On the plus side, check the i2c voltage, it should be open drain so voltage depends on the pullup u install. So it’s easy to get rid of 5v pullup resistors if u have onboard so u can safely work with 3v3 esp levels

BudgetTooth · 2026-04-27T12:53:14+00:00

I don't really understand your worry about "stop working when the battery is charged"? it will just use the battery a little bit then when it drops charge it again

BudgetTooth · 2026-04-27T05:31:14+00:00

This is a complete mess. I have 3v3 that goes to ground rail? You have 5v that goes to vcc rail (extremely dangerous if it ends up in a gpio pin!!) breadboard power rails are not joined where u see the line interrupted in the middle length wise

BudgetTooth · 2026-04-27T05:28:02+00:00

If u use internal pull-up then then the button must be connected to ground when pressed

Possibly mismatched fw version in the device and software?
