[BUG] d1_mini_pro errors on directly connected pins.

[mwitkow]

Describe the bug I'm trying to get the software running on a d1_mini_pro (as it has a detachable WiFi). I tried it now on two boards (same manufacturer) to see if it is not a hardware failure. I actually even made a custom PCB for it:

But now I'm troubleshooting why it doesn't work, and I'm finding that there are hwtest errors even on a direct connection between the pins of the board

"1" or "0" indicates ERROR, depending on test state. "-" is good.
Switching cio pins 5s HIGH -> 5s LOW -> input
then DSP pins 5s HIGH -> 5s LOW -> input, repeating
Disconnect cables then reset chip when done!

To Reproduce Steps to reproduce the behavior:

1. Get a d1_mini_pro
2. Change board = d1_mini in platformio.ini (otherwise i get device reports readiness to read but returned no data) Build. Upload. Build filesystem. Flash.
3. Change HW config to:

4. Connect pins directly using jumper cables.

5. 

6. Run `hw_test see errors.

7. See error

Expected behavior hw test passing since the pins are connected directly

Hardware (please complete the following information):

• Pump model, for example 54123
• 4 or 6 wires
• PCB type
• Level shifter type,

Software (please complete the following information):

• Version: latest master checkout.

For context,

I tried with board = nodemcuv2, but it can't upload the filesystem

I tried also setting board = d1_mini_pro, but filesystem reliably fails on:

Interestingly, the same firmware build and the same cables work on a d1_mini (non pro)

I searched the internet to see whether there is anything about D1 Mini vs D1 Mini Pro differences (e.g. when one of the ports is treated specially, but no dice.

Maybe one of the pins is kaputt

[mwitkow]

These are with 2 different D1 Mini Pro boards (although from the same supplier), exactly the same pair D3, D6 fails. Same pins and cables on the D1 Mini (non pro). This is the pinout for reference.

Any ideas what to change/test? I'd really like a board with external WiFi antenna.

Sorry, I don't know

Hey.

Did you found solution how to upload filesystem in to flash when board = d1_mini_pro selected ? I'm facing same problem :(

A fatal error occurred: Failed to write compressed data to flash after seq 2 (result was C400)

My lay-z-spa works with d1 mini but wifi range is terrible So i'm also looking to use d1 mini pro - but with no luck

Pozdrawiam Dawid :)

[intelx3]

Ok. I found solution how to flash correctly wemos d1 mini pro Just add board_build.ldscript = eagle.flash.8m7m.ld in platform.ini Without this compiler make a flash file littlefs.bin with size 4GB ! :) (there is bug in size calculation code).

But after that programm still not working :)

Hwtest pass ok

Start test. Seq begins with HIGH, then alters.

but there is nothing on the panel screen - no lights and no start beep.

i attached file witch /inputs input log.zip

Any ideas ?
