无法启用存储器的写访问

你好
 
 
 这太可怕了 - 太可怕了！
 
 你用'条目'做'解锁'吗？
 //解锁FLASH存储器（MASS序列）
 //在FLASH_PUKR（0x5062）中写入0x56然后写入0xAE
 
 
 你把0x10写入FLASH_CR2吗？
 0xFE到FLASH_NCR2
 开始扇区编程序列？



以下为原文





Hi


It is all horrible - truly horrible!

Do you do the 'unlock' with the 'entry' ?
     // unlock FLASH memory (MASS sequence)
     // Write 0x56 then 0xAE in FLASH_PUKR (0x5062)


Do you write 0x10 to FLASH_CR2
0xFE to FLASH_NCR2
to start the sector programming sequence?

嗨，
 
 我没有尝试进行块编程，我正在尝试使用WOTF命令进行字节编程，如文档PM0051中所述，并且我遵循4.6.1 ICP方法 - 第一种方法中解释的所有步骤，但我只能解锁eeprom内存



以下为原文





Hi,

i am not trying to do block programming, i am trying to do byte programming with the WOTF command as explained in the document PM0051 and i follow all the steps explained at the paragraph 4.6.1 ICP Methods - First method but i am able only to unlock the eeprom memory

好的 - 我确实说整件事情太可怕了。
 
 
 我能做的就是告诉你我为SWIM进入序列做了什么：
 设置STM8复位
 SWIM进入（4个长脉冲，4个短脉冲）
 延迟6ms
 发送SWIM通信重置（128 x HSI）
 延迟3毫秒
 将0xA0写入SWIM_CSR
 延迟3毫秒
 清除STM8重置
 延迟7ms
 停止STM8 - 在DM_CSR2中设置停顿位
 延迟7ms
 将0xA4写入SWIM_CSR
 延迟7ms
 解锁FLASH存储器（MASS序列）在FLASH_PUKR中写入0x56（0x5062）
 那么FLASH_PUKR中的0xAE（0x5062）
 
 这对我有用（但不是ST-Link的作用）
 
 另外，由于我系统中其他设备的编程序列，我的代码将在编程之前进行块擦除。



以下为原文





OK OK - I did say the whole thing is horrible.


All I can do is tell you what I do for the SWIM entry sequence:
Set STM8 reset
SWIM entry ( 4 long pulses, 4 short pulses)
delay 6ms
Send SWIM Comms reset (128 x HSI)
delay 3 ms
write 0xA0 into SWIM_CSR
delay 3 ms
clear STM8 reset
delay 7ms
stall the STM8 - set stall bit in DM_CSR2
delay 7ms
write 0xA4 to SWIM_CSR
delay 7ms
unlock FLASH memory (MASS sequence) Write 0x56 in FLASH_PUKR (0x5062)
then 0xAE in FLASH_PUKR (0x5062)

This works for me (but is not what the ST-Link does)

Also, because the programming sequence for the other devices in my system, my code will do a block erase before the programming.

很抱歉延迟回答但是我遇到了ADSL服务问题，我试着编写另一个相同类型的STM8，这次我还可以编写闪存程序存储器，这些存储器都使用我使用的代码以及更改你向我建议，所以我得出结论，第一台STM8有缺陷。
 
 但是，在两周内我应该收到一个st-link并使用它来验证第一个stm8是否有故障。
 问候



以下为原文





Sorry for the delay in answering but I had problems with the ADSL service, I tried to program  another STM8 of the same type and this time I could  write also the flash program memory, both with the code that I used and  also with the changes that you suggested to me, so I concluded that the first STM8 was defective.

However, in two weeks I should receive an st-link and using that i will verify if the first stm8 is faulty or not.
