Segger embedded studio does not display a static global variable in the watch window correctly

[weightwatcherphil]

I am using the nRF52840 development kit and running the SPI peripheral example in SDK 15.

I am having trouble displaying a static value in my watch window.

static const uint8_t m_length to the watch window it has the wrong value

If I change the code to

static uint8_t m_length it does not display a value.

If I change the code to

uint8_t m_length

it has the correct value.

I think all of these should display the same value in my watch window.

can you tell what I am doing wrong to get it to display incorrectly with the NORDIC supplied example for Segger Embedded Stuido.

This gives the  correct which is 0x03.

This gives the wrong value for m_length  0x3b

This does not give a value at all.

This is the version of Segger I am running.

This is my source file.  I started with SPI as an example and I am working on a FANSTEL BT840 evaluation board.

Hi Philip,

This has most likely to do with how SES IDE compiler handles optimization.

One recommendation is to make this case public, so maybe someone at the public forum could help as well.

This is the kind of question better asked in the Segger forums. They're very helpful over there and if there are bugs in SES,  will usually get them fixed in a release or two.

I am going to assume its optimizations for now.
