Recently I purchased another set of 5 devices of my Wemos D1 Mini Pro and continued development on my project. For the last 2 years I've been using the same 5 chips and they all have been working perfectly fine with both FOTA and standard Firmware Images. Now after I opened my first one I uploaded my firmware like I always do and them boom just a bunch of garbage on the screen. I thought that was weird then did the same to another net new one and one also is getting the same thing.. I plug in my old one and tested a 2nd old one and they both work.. I then used esptool.py to read_flash 0x200000 to read the first two megs then I write_flash 0 [BinFileSaved] and burned the full two megs onto the other new chips and nothing.. no dice... Anyone have any suggestions? Ill post my make file here shortly. I am using an outdated esptool.py but it works currently with my wemos d1 mini pro. I am using 32m-c1 configuration to burn my flash size but I think my wemos are actually 16 megabytes and not 32 megabits (4MB). Any help is appreciated.

I updated my Makefile to use Detect and adjusted my offsets to the 16MB profile and validated it on my old ESP. But my new one.. still no dice.. I wonder if the SPI is 26MHZ and my other one is 40MHZ and I need to adjust the init_data.bin, Im not sure yet.. Any suggestions?
PostScript: By the way, I love this forum but it seems to be pretty inactive lately. Did everyone migrate to another forum board?
