BlueNRG-MS fw 7.2c挂断

大家好。
在我们的项目中，我已经使用SPBTLE-RF模块工作了很长时间。我从未遇到过这些模块的任何问题。
但现在我们重新设计了PCB，并将使用直接放置在PCB上的BlueNRG-MS芯片（QFN外壳，16MHz分机振荡器+ 32768 Hz分机，低频振荡器，降压转换器有效）。
并且它不起作用...有趣的是FW升级没有任何问题（我们正在将fw图像嵌入到我们的软件中并且如果版本低于0x723则使软件变得更软）。 IFR（由我特别为我的硬件设计生成）更新和验证也没有任何问题（因为我理解上述两个动作都是由
BlueNRG-MS
bootloader）。但是当谈到配置芯片时 - 它会挂起。首先，我正在尝试配置DIV，ER和IR键。 DIV编程通过（
BlueNRG-MS返回0状态），但所有后续操作（ER，IR编程，间隙/ gatt初始化等）都失败 - 我没有收到BlueNRG-MS的任何中断，如果我发出的话，没有数据待处理手动中断。
有人知道芯片有什么问题吗？
提前感谢您的任何答案或提示。
PS：相同的代码完美地运行在具有SPBTLE-RF的旧PCB上。

Hello everyone.
I've been working for a long time with SPBTLE-RF modules in our project. I never experienced any problems with these modules.
But now we've redesigned our PCB and are going to use BlueNRG-MS chips directly placed on PCB (QFN case, 16MHz ext. oscillator + 32768 Hz ext. low freq. oscillator, step-down converter active).
And it doesn't work... Interestingly that FW upgrades without any problems (we are embedding fw image into our software and uptate chip softwarte if it's version is lower than 0x723). IFR (generated by me especially for my hardware design) is updated and verified also without any issues (as I understand both of the mentioned actions are done by
BlueNRG-MS
bootloader).But  when it comes to configuring chip - it hangs. First of all I'm trying to configure DIV, ER and IR keys. DIV programming passes (
BlueNRG-MS returns 0 status), but all subsequent operations (ER, IR programming, gap/gatt initializing, etc.) fail - I do not receive any interrupts from BlueNRG-MS and no data is pending on its side if I issue the interrupt manually.

Does anybody knows what can be wrong with the chip?

Thanks in advance for any answers or tips.

PS: the same code perfectly runs on older PCBs that have SPBTLE-RF.
