Hi Alan and all, Though I've never used nRF52 before, what we did for Bluetooth with LC823450-XGEVK are (1) Port proprietary Bluetooth stack to NuttX for our audio products. (2) Port bluekitchen/btstack to NuttX for a feasibility study of networking. LC82345-XGEVK has CSR8811 on the board which

Great! I was close to ordering a few pieces. But later I saw the shipping costs and gave up. So I wait until it is more accessible in the EU. Open source MCU+FPGA seems to be a powerful tool. czw., 18 cze 2020 o 03:56 Brennan Ashton napisał(a): > This is a chip that I have been excited about for

Hi Anjana, Did you add some flags (i.e. CELFFLAGS, CXXELFFLAGS and LDELFFLAGS) to scripts/Make.defs? The flags are needed to build elf modules. Regards, Masayuki 差出人: Anjana 送信日時: 2020年6月18日 14:38 宛先: dev@nuttx.apache.org 件名: ELF Application Example(apps/examp

Hello Team, I have added ELF Binary Loader support for RX65N target. I am currently testing my implementation using the apps/examples/elf/ example . When I enable the apps/examples/elf/ example application, and compile, I am getting the below error in symtab.c (Symbol Table) C:\cygwin64\home

I agree that access to low-level radio with documented registers is a big plus for Nordic. I hope other vendors will follow the same path (if not then we always have reverse engineering :P). For this reason, we should have a standardized interface for BLE single-chip solutions in Nuttx. A non-stand

Thanks Nathan. It's been interesting learning how to port and debug NuttX drivers. Hopefully I will be able to write something about it when I get the code accepted. It was helpful that I could port a driver used by the same chip peripheral IP block on other NuttX supported chips. I didn't have to

This is a chip that I have been excited about for a while since they are highlighting the open source tool support including the SoC and FPGA emulation with RENODE. Zephyr is the highlighted RTOS, but I thought it would be a great candidate for NuttX, especially since the MCU is a ARM M4 so the in

SDMMC write is working now too. So the driver can do the following: - Non-DMA read and write - DMA read and write in SDMA mode - 1 bit bus - 4 bit bus (widebus) - up to 25Mhz I'm going to work on cleanup, documentation, and PR next. I'll post a branch here when I get it somewhat cl

I saw that option recently and I don't really like it. It seems a debugging nightmare. What I actually like about Nordic is that at least it is possible to have an open-source low-level radio stack, which is not the case for Espressif since this is still closed source and undocumented. So I thin

Hi Mateusz, This is a great idea! Note that zGlue did exactly it, but they are using nRF52. Maybe Sony or Xiaomi has something similar implemented for NuttX and could help. Guys, are you hearing? Xiang? Masayuki? BR, Alan On 6/17/20, raiden00pl . wrote: > You can use Nordic's priorpiate BLE

Re: nrf51822 and BLE

You can use Nordic's priorpiate BLE stack (SoftDevice) and after a few hacks even Nordic SDK can be integrated with Nuttx. This gives you a certified BLE stack but it has a huge disadvantage - it is a closed source. Looking for bugs in such an environment is a nightmare. Some time ago I started wo
