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!
Show LessI want to use STM32 to program CY27410 through i2c. According to another topic, an NDA is needed. How do I receive an NDA from you? My email is zhz13456@163.com.
Thanks in advance.
Show LessHello,
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.
Show LessMB3773のウォッチドック監視時間(TWD)とリセット時間(TWR)ですが、
データシートには「最小、標準、最大」値が記載されておりますが、
同デバイスで変動することはありますでしょうか。
※例えば、1回目の動作時は標準値で、2回目の動作時は最小値になる可能性がある。
また、動作保証内の温度変動により許容差はありますでしょうか。
宜しくお願いします。
Show Less请问CY2071A(sop8封装)原厂配的开发套件是CY3670(已经停产)已经买不到了,现在cypress还在生产的开发套件哪一个型号可以支持读取CY2071A参数的?
Hi All,
We are using Cypress NOR Flash "S25FL128LAGNFV010" this along with RTOS configuration.
From total 16MB of flash, 14MB is user space and rest of 2MB is reserved.
Could you provide us latest copy of FTL and SLLD.
That will be great help to us.
