Hi @Dave ,
it gave me this when I process the code you instructed:
core-firmware.bin firmware_copy.bin differ: char 2, line 1
OK, let’s be elaborate:
- Now my core is flashing yellow endlessly and I cannot go back to normal mode via factory reset; it will flash white for many times and return to this yellow flash again.
- I make sure my core is in DFU mode: dfu-util -l, it gives me:
Found Runtime: [05ac:8218] devnum=0, cfg=1, intf=3, alt=0, name=“UNDEFINED"
Found DFU: [1d50:607f] devnum=0, cfg=1, intf=0, alt=0, name=”@Internal Flash /0x08000000/20001Ka,108001Kg"
Found DFU: [1d50:607f] devnum=0, cfg=1, intf=0, alt=1, name="@SPI Flash : SST25x/0x00000000/512*04Kg"
- I flash my core using
dfu-util -d 1d50:607f -a 0 -s 0x08005000:leave -D core-firmware.bin
It did the thing and now my core is flashing blue.
I input my wifi credential manually cuz the app is sometimes very buggy
Using a mac,
I go to CoolTerm,
I connect to my device,
input the credential
It saved the credential > connected > breathing cyan
I now go to Cloud IDE, add a core > work fine
Flash an example blinking LED
Magenta flashing coming up for 8 seconds
And … yellow flashing
WHAT DO I DO?
