bouffalo_sdk VS buildroot_bouffalo

I bought a bunch of the 16Mbit flash variant for an embedded project but sadly it looks like the firmware always gets corrupted on write, and have gotten no reply from Bouffalo

https://github.com/bouffalolab/bouffalo_sdk/issues/92

I tried looking through the source code of the SDK to get somewhat of an understanding, but it's taking too long for me to understand, so I'll leave it in your hands. gpio.h gpio.c gpio_reg.h

BouffaloLab has recently started bringing order to the chaos. They have created a new bouffalo_sdk where they're merging bl_mcu_sdk and bl_iot_sdk, the latter being the one to use for wireless. The README file lists which peripherals are currently supported. There's still work to be done, but it's good news they engaged into this endeavour.

The chip has complete-ish sdk here(https://github.com/bouffalolab/bouffalo_sdk) we use as "documentation". Datasheet and the reference manual are incomplete.

I don't think there is a "common solution". From my point of view, the Bouffalo Labs chipsets are not yet widely in use, at least not outside of china. However - as far as I can see, the USB host example code from the SDK interfaces the USB HID parts of the stack, too: https://github.com/bouffalolab/bl_mcu_sdk/blob/master/examples/peripherals/usbhost/usb_host.c

I just scoured the current main branch of https://github.com/bouffalolab/bl_mcu_sdk and can see the current HAL supports DMA, EMAC, flash, GPIO, MJPEG, PWM, RTC, encryption, timers, UART and USB. DAC and ADC's (audio) are implemented but not tested. I can also see there are BSPs for the LP core if you wanted to take advantage of it, with helloworld examples for all three, and finally there are some examples of using TensorFlowLite in the examples directory that you could build and try too.

Wifi/RF on bl616 is the same state as bl808. We are waiting for bouffalo to release support for it in bl_mcu_sdk: https://github.com/bouffalolab/bl_mcu_sdk/issues/85

Hi, I'm currently trying to install Linux on the Ox64 SBC following the instructions from this Github page. I did everything as instructed and all three binaries I had to flash, were flashed correctly. I then wrote the image to the µSD and tried to boot. But no matter what I do, I can't get any output on the serial port. When I try to open a connection with putty on ttyACM3 with 2M-baud, I get nothing. Same on ACM4. These boards were originally the 16Mb ROM versions which I ordered by mistake and then upgraded with 128Mb flash and µSD-slot. Does anyone here by chance play around with these boards as well and might have an idea what's the issue here ?

Also you might want to use https://github.com/openbouffalo/buildroot_bouffalo for Linux support which is where the main Linux development effort is happening

Following the instructions on the Github page found HERE
