唯一ID返回零

嗨，
 
 
 你可以排除2.因为这部分内存位置是写保护的，用户不能意外删除它。确保未启用ROP。

Hi,


you can exclude 2. because this part of memory location is write protected, user can't erase it by accident. Ensure ROP is not enabled.

嗨brazov2，
 
 
 感谢您的答复。
 我同意我不能删除UID。我想知道它是否可能没有在这批次上得到保障，我可能已经删除了它。
 
 我对ROP做了一些挖掘
 
 根据MCU配置窗口，禁用读出保护
。
 
 我可以在内存视图中读取选项字节，但唯一ID仍为空白。
 第一个位置0x4800（读出保护
 ROP）= 0
 根据我的理解，通过将0xAA写入0x4800来启用ROP，这也指向ROP被禁用。
 
 我附上了选项字节和唯一ID的屏幕截图（红色=选项字节，蓝色=唯一ID）
 
 任何进一步的指示表示赞赏。

Hi brazov2,

  
Thanks for your response.
I agree that I should not be able to erase the UID. I wondered if it may not have been secured on this batch and I might have erased it.
  
I have done a little digging on the ROP
  
According to the MCU configuration window, Read-out protection is disabled
.

I can read the option bytes in the memory view, however the unique id remains blank.  
The first location 0x4800 (Read-out protection
ROP) = 0  
From what I understand ROP is enabled by writing 0xAA to 0x4800, this also points to ROP being disabled.
  
I attached s screen shot of the option bytes and the unique id (Red= Option Bytes, Blue=Unique ID)
  
Any further pointers are appreciated.

我看了一下内存映射，ROP没有启用。数据表中指定的位置不存在96位唯一ID。看来你有一个狡猾的设备。奇怪的是，在上面一排的同一区域有96位。或数据表错误或设备狡猾。

I had a look on memory map, ROP it's not enabled. The 96 bit unique id is not present in the locations specified in the datasheet. It seems you have a dodgy device. The strange thing is that in the same area in the row above there are 96 bit. Or the datasheet is wrong or the device is dodgy.


brazov

再次感谢你的回复。
 
 我简要地看了一下另一块板（有不同的stm8），它还返回了零。
 
 星期一，我将查看保留区域中的96位是否可能是错误位置的唯一ID。我会比较一些板子。



以下为原文





Thanks again for your reply.

I had a brief look at another board (with a different stm8), It also returned zeros.

On Monday I will look to see if the 96 bits in the reserved area could be the unique id in the wrong place. I will compare a few boards.

地址
0x48B0到0x48BC在我可用的5个PCB上读取如下内容。
 
 
 71 8E 6D 92 6E 91 86 97 1A E5 E5 1A

 它们确实看起来像是独特的ID

They do look like they could be the Unique Ids

我做了一点研究：
 
 STM8S103K3 STM8S103F3 STM8S103F2：0x4865
 STM8S105xx：0x48CD [可能是0x48B0，因为此位置的数字似乎合理]
 
 STM8S207xx，STM8S208xx：0x48CD
 STM8S903K3 STM8S903F3：0x4865
 
 STM8L101xx：0x4925
 STM8L151x2，STM8L151x3：0x4926
 STM8L151xx，STM8L152xx：0x4926
 STM8L15xx8，STM8L15xR6：0x4926
 STM8L162R8，STM8L162M8：0x4926
 我确实发现一个论坛帖子暗示2009年底之后制作的设备有唯一ID：http：//translate.google.com/translate？hl = en＆amp; sl = zh-CN＆amp; u = http：//bbs。 eeworld.com.cn/thread-254362-1-3.html&ei=Ro-JTpqrBMm90QX837DUDw&sa=X&oi=translate&ct=result&resnum=1&ved=0CCUQ7gEwADgU&prev=/search?q%3DSTM8 ％2Bunique％2Bid％26start％3D20％26hl％3Den％26safe％3Dactive％26client％3Dfirefox-A％26sa％3DN％26rls％3Dorg.mozilla：EN-US：非官方％26biw％3D1106％26bih％3D928％26prmd％3Dimvns
 
 我想知道我是否有旧设备，如果这是真的。



以下为原文






I have done a little research:

STM8S103K3 STM8S103F3 STM8S103F2: 0x4865
STM8S105xx: 0x48CD [Possibly 0x48B0 as the numbers in this location seem plausible]

STM8S207xx, STM8S208xx: 0x48CD
STM8S903K3 STM8S903F3: 0x4865
  
STM8L101xx: 0x4925
STM8L151x2, STM8L151x3: 0x4926
STM8L151xx, STM8L152xx: 0x4926
STM8L15xx8, STM8L15xR6: 0x4926
STM8L162R8, STM8L162M8: 0x4926
I did find a forum thread suggests that devices produced after the end of 2009 have the Unique ID: http://translate.google.com/translate?hl=en&sl=zh-CN&u=http://bbs.eeworld.com.cn/thread-254362-1-3.html&ei=Ro-JTpqrBMm90QX837DUDw&sa=X&oi=translate&ct=result&resnum=1&ved=0CCUQ7gEwADgU&prev=/search?q%3DSTM8%2Bunique%2Bid%26start%3D20%26hl%3Den%26safe%3Dactive%26client%3Dfirefox-a%26sa%3DN%26rls%3Dorg.mozilla:en-US:unofficial%26biw%3D1106%26bih%3D928%26prmd%3Dimvns

I wonder if I have older devices and if this is true.

我的供应商已确认其中一批产品缺少唯一ID。
 
 我将确认我的设备是否属于此批次。



以下为原文





My supplier has confirmed one of the batches was missing the unique id.

I will confirm if my devices are part of this batch.

我用不同的设备替换了STM8（来自RS）
 
 我明白了：
 唯一ID [0x48CD] = 0x0
 唯一ID [0x48CE] = 0x3D
 唯一ID [0x48CF] = 0x0
 唯一ID [0x48D0] = 0x60
 唯一ID [0x48D1] = 0x17
 唯一ID [0x48D2] = 0x36
 唯一ID [0x48D3] = 0x30
 唯一ID [0x48D4] = 0x34
 唯一ID [0x48D5] = 0x32
 唯一ID [0x48D6] = 0x31
 唯一ID [0x48D7] = 0x35
 唯一ID [0x48D8] = 0x36
 这必须是批处理问题。
 失败的设备都有：05K6U6 9YBNG VG MYS 917
 写在上面。
 我还没有听说过ST吗？



以下为原文





I have replaced the STM8 with a different device (from RS)

I get:
Unique ID [0x48CD]= 0x0
Unique ID [0x48CE]= 0x3D
Unique ID [0x48CF]= 0x0
Unique ID [0x48D0]= 0x60
Unique ID [0x48D1]= 0x17
Unique ID [0x48D2]= 0x36
Unique ID [0x48D3]= 0x30
Unique ID [0x48D4]= 0x34
Unique ID [0x48D5]= 0x32
Unique ID [0x48D6]= 0x31
Unique ID [0x48D7]= 0x35
Unique ID [0x48D8]= 0x36
This must be a batch problem.
The failing devices all had: 05K6U6 9YBNG VG MYS 917
written on the top.
I have not heard from ST yet?

现在看来还好，看着我的：

Note: the original post contained a large number of threaded conversations and was only able to be migrated to the 9th level

我收到了ST的以下信息：
 
 
这些独特的ID在STM8产品的生产过程中仅在2010年下半年开始生产。如果你得到带有标记的样品，例如MYS 11xx，则应该没问题。 11代表年份，xx代表本周。



以下为原文






I have received the following from ST:


The unique ID's are being programmed inside the STM8 products during their production only from second half of 2010. If you get samples with marking ending by for example MYS 11xx, those should be OK. 11 stands for the year, xx for the week.
