This Week in #RustLang

As we've seen, #NuttX has its own HAL for #BL602 ... Which differs from BL602 IoT SDK ... So we expect some quirks

https://github.com/apache/incubator-nuttx/tree/master/arch/risc-v/src/bl602

Blinking the #BL602 LED ... Works on #NuttX BASIC too! 🎉

After fixing GPIO Output, #NuttX now blinks the Blue LED (GPIO 11) on PineCone #BL602! 🎉

https://github.com/lupyuen/incubator-nuttx/pull/1/files

We mod #BL602 #NuttX to set the GPIO Output Enable Register at 0x40000190 (BL602_GPIO_CFGCTL34)

https://github.com/lupyuen/incubator-nuttx/pull/1/files

#BL602 IoT SDK says that GPIO Output Enable Register is at 0x40000190 (GLB_GPIO_CFGCTL34) ... Let's set this register in #NuttX

https://github.com/lupyuen/bl_iot_sdk/blob/master/components/bl602/bl602_std/bl602_std/StdDriver/Src/bl602_glb.c#L1990-L2010

#BL602 Reference Manual says we should set the GPIO Output Enable Register ... But it's missing from the docs ... Where is the register? 🤔

https://github.com/bouffalolab/bl_docs/tree/main/BL602_RM/en

#NuttX configures #BL602 GPIO 11 (0x40000114) with GPIO Input Disabled ... But it doesn't Enable GPIO Output 🤔

https://github.com/apache/incubator-nuttx/blob/master/arch/risc-v/src/bl602/bl602_gpio.c#L59-L133

#NuttX writes correctly to the GPIO 11 Output Register at 0x40000188 (BL602_GPIO_CFGCTL32)

"Peek" and "Poke" a GPIO Output Register on #BL602 #NuttX BASIC ... To flip the LED on and off!
