bouffalo_sdk VS versaloon

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

I'm using this diy stm32 bluepill project to turn it into a JTAG debugger: https://github.com/zoobab/versaloon. I think it's pretty cool!

You could even do a JTAG dongle yourself. For example, the dirt cheap STM32-based Blue Pill in combination with the Versaloon Firmware does exactly that. Combine it with the SVF route, and you have a very cheap alternative.
