用的是TUYA OS，设备的固件也需要烧录到涂鸦模组芯片里
1.请问目前用的BK_Writer 烧录工具，重新烧录时无法保留授权码，会全部擦除覆盖，请问如何解决？
2.请问烧录时代码中需要加入授权码吗？如果模组已经自带授权码了
3.另外芯片我选了T2对吗？好像没有对应的BK7231NSP选项

Re: 【操作指南】联网设备的烧录授权
请问用的是TUYA OS,模组TCS905-U,烧录软件用的是BK_writer.
1.请问如何只擦除固件，原来的授权码保留？
2.请问如果是用这个BK_Writer软件烧录，新的固件代码里不带授权码，是否可以？如何操作，目前试了下好像是无法连接联网
3.请问如果还是用这个烧录软件，新的固件代码里含有授权码? 那烧录完会取用新的授权码吗？

Re: 【操作指南】联网设备的烧录授权
用的是TCS905-U模组，内置是BK7231NSP这款芯片，通过代码的方式将授权信息写入到 flash，每次都得把授权码写入代码中吗？有没有办法反复烧录可以不擦除授权码在开发阶段？

Re: the SPI communications “hangs” randomly-urgently
but every SPI can transfer data in full duplex. we final have found the problem in the Tuya System and could manage to apply a solution that works for us. Please find attached the updated document. could you please check and change the TUYA System as well? thank you

the SPI communications “hangs” randomly-urgently
the SPI communications “hangs” randomly. Please find attached the analysis of the problem and the modified tuya_app_main.c from the quickstart demo. can you check this on a T2 Demo Board and can you run the spi in a Loop for a few minutes at least and with the function “tkl_spi_transfer(SPI_ID, spi_...
