Hi,
I have CNCv3 on Wemos D1 R32 board, and I have it perfectly working with LV8729, but unfortunately when I plug in S109 it does not work for some reason, it is not able to boot, I get this error when debugging verbose:
rst:0x1 (POWERON_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT)
invalid header: 0xffffffff

Fun fact, I get same error when I try to plug TMC2209
When I boot with LV8729 plugged in I get following status and it all works as a charm:
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

load:0x3fff0030,len:1240
load:0x40078000,len:13012
load:0x40080400,len:3648

One maybe important fact is that I actually did not get Wemos D1 R32, but aliex seller sent me ESPDUINO32, they look the same, and it works with LV drivers
