STM32CubeMx freeze if DMA Event for SPI4 is activated

CKage.1 · ‎2021-07-13

Hello,

if I generate with CubeMX 6.2.1 (Windows 10 or Ubuntu 20.04) the attached project, it freezes with the following screen:

MCU: STM32H7A3V(G-I)Tx

2021-07-13 09:20:39,936 [ERROR] runtime:60 - Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:
==> varName  [in template "ip_c.ftl" at line 420, column 82]
 
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use [#if myOptionalVar??]when-present[#else]when-missing[/#if]. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??

Does anyone have an idea how I can get around this?

Hello @CKage.1,

Let me first thank you for your feedback and welcome you to the STM32 Community :smiling_face_with_smiling_eyes:

Backing to your project, you're using "Enable event" for the "SPI4_TX" and "SPI4_RX" DMA request as well as the "Generate peripheral initialization as a pair of .c/.h files per peripheral" option:

When using "Enable event" for the DMA Requests when "Generate peripheral initialization as a pair of .c/.h files per peripheral" option is enabled, STM32CubeMX will generate code with this exception.

This misbehavior was reported internally to be fixed. The fix will be available as soon as possible, I'll surely keep you posted with the updates.

Thus, what I can propose in this case is whether to not to use the "Enable event" or uncheck "Generate peripheral initialization as a pair of .c/.h files per peripheral" option, normally your project will be correctly generated.

Sorry for any inconvenience that this may cause.

Khouloud.

Hello Khouloud,

Thank you very much for the quick feedback.

I can confirm that the problem can be worked around by decativating "Generate peripheral initialization as a pair of .c/.h files per peripheral" or not using the events.

With this I can continue working for now and hope for a new version soon :)

Best regards,

Christian
