> I think it's not related to RF parameters, since I also flash wifi example from BL offical SDK, it works well. And same as acassis, I use command tool and not flash any other binary. The official BL SDK uses the device tree to save the RF parameter information, but NuttX currently does not support the device tree. Therefore, when linking the NuttX of BL602, the linker script will reserve 1K space at the beginning of 0x400 in the generated bin to save the RF parameters obtained from the device tree. When using the official download tool to download the code, the tool will automatically parse the specified device tree file and find the RF parameter, convert it into a TLV format raw binary data, and write it directly into the 0x400 offset of the bin file. As far as I know, third-party tools currently do not support automatic patching of TLV RF parameters in the bin file. ``` $ hexdump -C -s 0x400 -n 512 nuttx.bin 00000400 42 4c 52 46 50 41 52 41 00 00 00 00 00 00 00 00 |BLRFPARA........| 00000410 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00000600 ``` -- This is an automated message from the Apache Git Service.
