[Solved][Duet2Wifi] WiFi SPI Timeout after removing SBC Mod
-
@keyz182 did the firmware flash sucessfully?

M997 S0too which correctly reports 3.3 after a restart andM122. -
@keyz182 ok to the UART comms to the module is working. Have a look at the schematic here
you can test the continuity for the SPI pins
-
@t3p3tony Continuity to the MCU for MOSI, MISO and SPCK, any other pins I should check?
-
@t3p3tony There's continuity on all three.
-
@keyz182 also the ESP_DATA_RDY and NPCS0
-
@keyz182 is the SPI timeout message consistent? That message is sometimes produced spuriously, especially when sending a M587 command for the first time after re-flashing the WiFi firmware.
-
@t3p3tony Continuity (through 2.2KOhm) on both which seems to tally up with the schematic.
@dc42 It's consistent. Right after a flash, leaving it a while, rebooting, etc, all the same as soon as I try
M587orM122.Connecting...

@keyz182 can you try sending M552 S0 before trying M587?
I find its sometimes not happy sending the wifi details when in S1 -
@jay_s_uk OK, that worked. Is that documented behavior that I've just misread? I swear I've always done
M552 S1before anyM587commands. -
@keyz182 the step by step guide does say to put it in S0 mode first.
Its also they way I've documented it on all the STM32/LPC port support pages. -
@t3p3tony what do ESP_DATA_RDY and NPCS0 for? can this to pin connect to GND or 3.3V pull up, thanks for reply
