Serial Console

[KTechDev4213]

What settings should be used for the linux serial console?

[Fishwaldo]

2000000 Baud, 8N1

What flow control?
Because putty is not showing anything.

No flow control. Maybe you selected the wrong com-port?

[KTechDev4213]

I opened both at the same time with putty

Here is a list of things that you could try to solve it:

• check wiring
• check the settings of dev cube
• check log of dev cube during flashing
• try a different serial probe

[KTechDev4213]

DevCube said it successfully flashed it. Is it still possible that it was not flashed properly?

[Fishwaldo]

Please make sure you are using version 1.8.3 of Devcube. Older versions have a issue.

[KTechDev4213]

Where can I find version v1.8.3?
I have only found v1.8.4 on their website?

[KTechDev4213]

I used version v1.8.3 and I still was not able to get a serial console.

Used v1.8.4 and the latest FW from https://github.com/openbouffalo/buildroot_bouffalo/releases/tag/v1.0.1 but i also didn't get a working serial console (neither 2000000 Bd or 115200 8N1 etc is working) for Linux on GPIO 16/17 (Pin 31/32), just get carbage on GPIO 14/15 (Pin 1/2) used for the programming 🤷

1.8.4 is broken with the current buildroot. You have to use 1.8.3. Get Outlook for iOS<https://aka.ms/o0ukef>

@Fishwaldo thnx a lot, with 1.8.3 i was able to get "something" from GPIO 16/17 (Pin 31/32), but it's still just carbage. Seems my USB-to-Serial Converter based on CP210x isnt capable to operate above 115200 Bb...
According to the data sheet a FT232 based could do up to 3M Bd, but Amazon just listed converters with FT232BL/RL which are only able up to 1M Bd ... any suggestions for a working converter capable for 2M baud? thnx

[jbrunk1966]

Bought a CH340G based USB-to-Serial Converter at Amazon for 5 bucks this is able to operate at 2.000.000 Bd :woohoo:
