Im using the V1.1 upload protocol, and it works okay up to the point where the transfer is initiated (see log, skipping the weird string and connect parts).
UART1 RX: “comok 1,67-0,NX4827T043_011R,162,61488,E4605836471D4531,16777216<\xFF><\xFF><\xFF>”
INFO,DISPLAY,Display confirmed firmware update. Continue process.<\r><\n>
UART1 TX: “whmi-wri 828488,115200,0<\xFF><\xFF><\xFF>”
UART1 RX:"<\x1A><\xFF><\xFF><\xFF>"
Here, the document indicates that 0x05 should be returned, but the error codes indictes and invalid variable. I’ve checked the file size (ok) and the baud raute obviously work because the “comok…” string is correctly transmitted. Is the size too big? The file contents are not much changed from the version that is currently running though, and its far from the capacity indicated by the comok string if that is worth anything.
Couldn’t find any further info googling, but I hope someone here has some insight.
Im a bit lazy, but if neccessary I could create a standalone minimum application but since the thing is built into some kind of device I’m currently trying to avoid that.
