采用SPI x4的Spartan 6多重启动和后备CRC错误

对不起，我犯了一个错误：SPI x1效果很好！



以下为原文

Sorry, I've made a mistake: SPI x1 works well!

嗨，
有谁能够帮助我？
是否有SPI x4可用的示例？
谢谢！
最好的祝福

Hi,
 
can anybody help me? Is there an example with SPI x4 available?
 
Thanks!
Best regards

嗨，
感谢您在Xilinx论坛上发布您的查询。
请按照以下步骤操作。
1）使用链接中的SP605多重引导设计。
但请确保您使用的是设计指南中提到的相同ISE版本。
2）现在，您需要在此设计中进行的唯一更改是将x1模式更改为x4模式以进行ICAP多重引导重新配置。
3）在编程prom时，工具会询问SPI的x1或x4设置。
确保在那里给出正确的设置。
3）如果您在生成mcs文件或编程闪存时收到任何警告，请告诉我。
在对回退的查询中，您可以将-g configFallback设置为Enabled以启用回退重新配置。
但是我希望你不要在比特流中插入多重启动设置。
谢谢，
谢谢，AnirudhPS：请将此标记作为答案，以防它有助于解决您的问题。如果帖子引导您找到解决方案，请给予赞誉。

Hi,
 
Thanks for posting your queries on Xilinx forums.
 
Please follow the below steps.
1) Use the SP605 multiboot design from the link - link. However make sure that you are using the same ISE version as mentioned in the design guide.
2) Now the only change you need to make in this design is to change the x1 mode to x4 mode for ICAP multiboot reconfiguration.
3) While programming the prom the tool asks for the x1 or x4 setting for the SPI. Make sure you give the correct setting there.
3) Let me know if you are getting any warnings while generation of mcs files or while programming the flash.
 
On your query on the fallback, you can give the -g configFallback as Enabled to enable the fallback reconfiguration. However i hope you are not inserting the multiboot settings in the bitstream.
 
Thanks,
 
Thanks,
Anirudh

PS: Please MARK this as an answer in case it helped resolve your query.Give kudos in case the post guided you to a solution.

有答案（除了在论坛上的其他地方）？
以防万一，这是我对标题的解码：
意思是：
FFFFFFFF：虚字AA995566：同步字31E1FFFF：[001] [1 0] [001 111] [0 0001] =>添加。
0xF：用最大值写入CWDT（cfg看门狗定时器）。

0x13：写入Gen1（多引导16 LSB）32816B10：[001] [1 0] [010 100] [0 0001] =>添加。
0x14：写入Gen2（SPI命令和多重启动8个MSB）32A14000：[001] [1 0] [010 101] [0 0001] =>添加。
0x15：写入Gen3（黄金16 LSB）32C16B00：[001] [1 0] [010 110] [0 0001] =>添加。
0x16：写入Gen4（SPI命令和黄金8个MSB）32E10000：[001] [1 0] [010 111] [0 0001] =>添加。
0x17：用val写入Gen5。

0x10：写入HC_OPT_REG（房屋清洁选项寄存器），init_skip = 0（不跳过初始化）30A1000E：[001] [1 0] [000 101] [0 0001] =>添加。
0x5：写入CMD，cmd = 0xE => IPROG命令2000：[001] [0 0] [000 000] [0 0000] => NOP 2000：[001] [0 0] [000 000] [0 0000] =

（参见附带的Spartan 6配置指南的摘录部分，从配置详细信息部分中提取，用于MODE寄存器）
这条线：
33012100的bus_width = 0（乘1），
这意味着“重启”的SPI宽度为1（而不是4）。
还要检查hex文件中比特流的地址。
不确定它们是否符合您的要求。
当我尝试使用Spartan 6进行多重启动时，我发现了工具和示例的一些问题。
似乎他们可能尚未解决。
希望能帮助到你。
我经常不上论坛。
任何问题都可能无法解答。
对于那个很抱歉。

(see extracted part of the Spartan 6 configuration guide attached, extracted from configuration details part, for MODE register)
 
The line :
33012100 has the bus_width=0 (by 1),
This means that the SPI width for the "reboot" is by 1 (not by 4).
 
Check also the addresses for your bitstreams in the hex file. Not sure they match with what you wanted.
 
When i tried multi-boot with the Spartan 6, I discover some problems with the tools and the examples. Seems that they might have not been resolved.
 
Hope it helps.
I do not come on forum often. Any questions might be unanswered. Sorry about that.
 

只是忘了说对于类型1标头包，16个MS位是操作的类型，地址等。
16个LS位是数据部分（与您想要的设置匹配的部分）。
研究配置细节以了解更多信息（是的，我知道，它应该在没有研究的情况下工作）。



以下为原文

Just forgot to say that for type 1 header packet, the 16 MS bits are the type of the operation, the address, etc.
The 16 LS bits are the data section (the one to match with the settings you want).
 
Study the configuration details to know more about it (yes I know, it should work without studying that).
 

嗨elewis_reg_tb，
非常感谢你。
但你的标题与我在第1篇文章中的标题相同。
不幸的是它不起作用 - 我不知道为什么。
SP605评估板无法正常启动。
尝试加载配置后，出现红色配置错误指示。
有提示的其他人吗？
提前致谢！



以下为原文

Hi elewis_reg_tb,
 
thanks a lot for this. But your header is the same as mine in post #1. Unfortunately it does not work - and i don't know why.
 
The SP605 eval board will not boot properly. After trying to load the configuration, the red config error led appears.
 
Anyone else with a hint?
 
Thanks in advance!

你有没有尝试过 ：
33013100而不是33012100？
我可能错了，但是要将buswidth字段更改为4，必须将33012100的“2”更改为“3”，以便将SPI 12的位12:11设置为“10”。
SPI x1的原始标题似乎没问题（不适用于x4）。



以下为原文

Have you tried :
33013100 instead of 33012100?
 
I may be wrong but to change the buswidth field to 4, you must change the "2" of 33012100 to a "3" in order to have bits 12:11 set to "10" for SPI x4.
Original header seems OK for SPI x1 (not for x4).
 

最终我找到了使SPI x4编程工作的方法。
最好的方法是基于sp605多引导参考设计，该设计在命令行模式下生成所有文件。
来自此sp605的批处理文件被设置为为SPI x1生成比特流：要成功的关键点是将spi_buswidthBitgen开关设置为1（SPI x1）以进行黄金和多重启动 - 不是4！
当你选择它时，4 Bitgen做了疯狂的事情，因为它有bug，Xilinx不再关心ISE。
因此，保持Bitgen的设置与SPI x1配置相同。
唯一的更改必须在引导头中完成：
1）General2寄存器3281，原来0340我改为6B40（SPI Fast quad read command＆amp; 40 as multiboot addres）
2）General4寄存器32C1，原来是0301我改为6B01（SPI Fast quad read command＆amp; 01 as golden addres）
3）模式寄存器3301，原来2100我改为3100（重启后设置SPI x4）
我的启动头看起来像这样：
FFFFFFFFAA99556631E1FFFF3261000032816B4032A1000032C16B0132E1000030A10000330131003201001F30A1000E2000200020002000
我检查了在SPI x1模式下FPGA的配置大约需要260ms（clk = 26MHz）。
在实施上述变更后，由于SPI x4，需要60ms。
然后我损坏了多引导比特流并且它被强制从黄金启动：它也需要60毫秒来配置黄金。
现在，享受SPI x4模式！
谢谢Xilinx一无所获。



以下为原文

Eventually I found the way to make SPI x4 programming working.
 
The best way to start is to base on sp605 multiboot reference design which generates all files in command line mode. The batch files from this sp605 are set to generate bitstream for SPI x1: the key point to be sucessfull is to keep spi_buswidth Bitgen switch set to 1 (SPI x1) for golden and multiboot - NOT 4 !!! When you select it as 4 Bitgen does crazy things as it has bugs and Xilinx does not care any more about ISE. So keep settings for Bitgen in the same way as for SPI x1 configuration. The only changes have to be done in boot header: 
1) General2 register 3281, originaly 0340 I changed to 6B40 (SPI Fast quad read command & 40 as multiboot addres)
2) General4 register 32C1, originaly 0301 I changed to 6B01 (SPI Fast quad read command & 01 as golden addres)
3) Mode register 3301, originaly 2100 I changed to 3100 (SPI x4 set after reboot)
 
My boot header looks like this:
FFFFFFFF
AA995566
31E1FFFF
32610000
32816B40
32A10000
32C16B01
32E10000
30A10000
33013100
3201001F
30A1000E
20002000
20002000
 
I checked that in SPI x1 mode configuration of the FPGA takes roughly 260ms (clk=26MHz).
After implementing changes discribed above it takes 60ms because of SPI x4.
Then I corrupted multiboot bitstream and it forced to boot from golden: it also took 60ms to configure from golden.
 
Now, enjoy SPI x4 mode!
Thank you Xilinx for nothing.
 

上述解决方案的一个补充：当您使用IMPACT将为SPI x4（引导标头+ golden + multiboot）准备的MCS文件编程到SPI闪存中时，您必须在选择SPI闪存时选择SPI数据宽度4。
至少在我的主板上有Winbond W25Q64FV的情况。
如果您编写完全相同的mcs文件但数据宽度不是4，则FPGA将无法顺利配置。
在我看来，编程工具不应该分析它写入内存的数据，而它似乎就是这样。
在这个SPI x4模式下有很多陷阱，但如果你遵循这个方案，至少它是有效的。



以下为原文

One suplement to the solution above: when you program the MCS file prepared for SPI x4 (boot header + golden + multiboot) into your SPI Flash using IMPACT then you have to select SPI data width 4 when you select your SPI Flash. At least it was in the case of Winbond W25Q64FV I have on my board. If you program exactly the same mcs file but data width is other than 4, then the FPGA will not configure sucsefully.
In my opinion the programming tool should not analyse the data it writes to memory while it seems that it does.
Plenty of traps in this SPI x4 mode but at least it works if you follow this scheme.
