无法在5071B上加载5070B仪器状态

Hello Barrie，>开发分析器似乎表明运行的唯一代码是>少数事件驱动的串行输入函数。
查看这些代码线程>显示它们定期运行而没有问题 - 完全符合>预期。
我找不到任何其他代码>线程中的任何生命迹象，包括一个简单的循环时间display.did我理解你的程序确实停止执行但是从VEE开发它仍然似乎运行？
因此，当您使用绿色框（执行流程）跟踪当前活动的vee对象时，您会看到一些浅绿色的对象，并且Ve似乎在这里挂起？如果是这样，并且您的“事件驱动的串行输入函数”指向我指向该方向，
由于vee在运行时无法执行某个功能，因此我很难假设死锁：如果函数A正在执行并且事件中断该执行并再次尝试调用函数A，则会发生此死锁 - 没有任何错误消息等。
如果你将事件用作一种中断例程，请记住以下事项： - 使中断例程尽可能短而快（在旧的8088上也是如此 - 并且仍然是这样） - 不要从中断例程中调用任何函数
。
一个解决方案通常是在这里举起一个标志并在'并行'的vee线程上测试它。
cou可以安全地调用所需的功能。我希望这是你的问题，我可以给你一些帮助，但GeorgGeorg Nied Software-Development Hansestr。

did I understand you correctly that your program did stop executing but from VEE-development it still seems to run?
So when you trace the currently active vee objects with the green boxes (execution flow) you see some objects that are light green and vee seems to hang here?

If so, and your 'event driven serial input functions' pointed me to that direction, I stromgly assume a deadlock due to the fact that vee cannot execute a function when it is already running: if function A is executing and an event interrupts that execution and tries to call function A again this deadlock occurs - without any error message or such.
If you use events as kind of interrupt routines keep trhe following things in mind:
- make the interrupt routine as short and quick as possible (this was true on the old 8088 - and is still)
- do not call any functions from the interrupt routine. A solution is often to raise a flag here and test it on a 'parallel' vee thread. There cou can safely call the desired function.

I hope that was your problem and I could give you some assistance



best regards,

Georg

嗨戴夫，这很不寻常。
我认为我们总是支持同一工具上的固件转速之间的至少一级向后兼容性。
这意味着如果你保存一个转速为1的状态，它应该在转速2上召回，但也许不在转速3上。即便如此，我认为大多数转回几转。请注意，这不适用于型号。
保存在B上的文件可能无法在C上调用，或者保存在8719D上的文件可能无法读入8719ES.Joel -----原始消息-----来自：Dave Evanson [mailto：devanson@zetex.com]

  Hi Dave,
     That's unusual.  I thought we always support at least one level of backward compatibilty between
firmware revs on the same instrument.  That means if you saved a state with rev 1, it should recall on rev 2,
but maybe not on rev 3.  And even so, I thought most went back several revs.
Note that this is not true with model numbers.  Files saved on a B may not recall on a C, or files saved
on an 8719D may not read into an 8719ES.

Joel

I'm not familiar with the 5070B or 5071B but it could be that the firmware
in the instruments is different and therefore it may not be possible to load
a 5070B instrument state on a 5071B.


After upgrading the firmware on a HP8719ES Network Analyser I found it would
not load old instrument states I has saved off before.

All, - and apologies for this non vee mail but am very stressed!!!

Does anyone know how to get a state file from a 5070B to work on a 5071B?-
They are  the same instrument, but the 5071 is an 8.5GHz variant.

When trying to load the state it just says 'recall failed'.

If anyone has any experience of this or ideas, please, please mail of call
me..

Thanks, - and sorry again to the vee guys

Alex.

不要总是相信这是真的。
至少有一种仪器（Iforget类型，但我认为它是一个示波器），如果你从一个固件版本中保存了一个状态并用下一个FWRev将它加载到仪器中，那么仪器会烧坏一个组件！

Don't always trust that to be true.  There was at least one instrument (I
forget the type, but I think it was a scope) where if you saved a state from
one firmware revision and loaded it into the instrument with the next FW
Rev, the instrument would burn up a component!  (The state was transmitted
as a binary image - the map bits changed such that the old state now told
the instrument to drive High/Low at the same time.)
