RE: new m5stack: Failed to write to target RAM (result was 01070000)
Image of reverse side of Atom Hub Proto board?
The product information for the Atom Hub Proto (https://docs.m5stack.com/en/atom/atomhub) is really useful, but it would be really useful to see the layout on the reverse side of the proto board itself.
Is there an image that you can share?
RE: Have I bricked my M5 Atom?
Many thanks for your rapid reply and your helpful "debugging" questions.
My M5 Atom is working just fine now, even the GPIOs I thought I might have fried :-)
Have I bricked my M5 Atom?
I accidentally connected two output pins - G22 & G19 - together without an intermediate load, and since that happened the indicator LED isn't operating, so it's hard to know what boot state the device is in.
I did re-flash the device with the V1.9.2 release of UIFLOW using M5Burner and that completed successfully. But the problem still remains.
I'm assuming that it is the flash memory of the ESP32-PICO-D4 chip that is being programmed. In which case that would suggest the chip is still alive.
Any thoughts / similar experiences / solutions out there?
