我们在调试过程中发现STM32F427IIH6TR主机can perform 1-bit ECC correction and 2-bits ECC detection，

但是NAND Flash S34ML02G200BHI000 datasheet with 4-bit ECC per 528 bytes (×8) or 264 words (×16)，从 Flash datasheet变更历史记录里面有提到ECC 从1bit变为4bit

请问以上有什么解决方案可以让NAND Flash和STM32之间ECC可以正常使用？谢谢！

Hello,

I'm making wireless switch USB with CYRF8935 module and MCU (ATmega48).

And I have some troubles with C coding.

I had read the datasheet several times, and set the registers according to the guide.

1)

Should I program the register in specific order?

I had just programmed register from 1 to 50 in order. I guess it's the biggest problem (maybe).

2)

CYRF8935 is programmed byte by byte, but some register(Reg52) has both read only and writable bit in one byte.

How should I program registers like this case?

3)

The packet structure is preamble + sync word + trailer + FIFO data. FIFO data are wrote in register 50, but I can't find the registers to program preamble and trailer.

Which registers are used to program preamble and trailer?

I'm beginner in transceiver and MCU, so I have too many troubles with programming. I attach the C code of Tx.

Thank you for reading. I really appreciate any help.

Thanks.
