Reading wemosD1

Open quintendewilde opened this issue 8 years ago • 2 comments

Hi, I'm following your work on hack a day.

I've succesfully flashed the wemos. But when I minicom or look thru arduino serial I get:

�!����1�)m�1�)�!��� Restore init data. �!����1�)m�1�)�!��� Restore init data. �!����1H)m�1�)��� Restore init data. I get all other different things on other baudrates but this one gives me the restore init data.

What can I do?

UPDATE: Further reference: I'm using an Wemos D1 Mini Pro I erased the flash succesfully, initialized the esp_data_default (sdk) And reflashed with : esptool.py --port /dev/cu.SLAB_USBtoUART --baud 115200 write_flash 0x00000 nodemcu-master-9-modules-2016-05-05-20-09-20-integer.bin

I get following on 115200 baud

`load 0x40100000, len 27616, room 16 tail 0 chksum 0x3b load 0x3ffe8000, len 2252, room 8 tail 4 chksum 0x44 load 0x3ffe88cc, len 8, room 4 tail 4 chksum 0xd1 csum 0xd1 system param error 0d f0 00 00 52 a0 bf 27 35 14 9c 13 0c 37 30 60 14 cc a6 e0 92 11 82 a3 00 90 88 c0 47 a8 03 0c ...

What is the difference between the Wemos D1 Mini that I used and the D1 Mini Pro? Maybe it has a different memory map, and you can't use the image that I did? I looked really quickly, and it seems that it's got a different usb-serial chip, and a different flash rom (16 MB! Cool.)

Have a look in the readme file to see which modules I compiled in (important is the MQTT one, naturally) and then follow along with the Pro install instructions: https://www.wemos.cc/tutorial/get-started-nodemcu.html

Let us know if that works?
