reg addr's for GTZC_TZSC_MPCWMxANSR GTZC_TZSC_MPCWMxBNSR

[Hedley]

The doc and SVD file don't have a reg at offset 0x44 (GTZC_TZSC_MPCWM3BNSR).

Since GTZC_TZSC_MPCWM3ANSR @0x40 exists, via symmetry I would expect B also at 0x44.

The doc does say this:

GTZC_TZSC external memory x non-secure watermark register 1

(GTZC_TZSC_MPCWMxANSR)

Address offset: 0x030 + 0x008 * (x-1), (x = 1 to 3)

and

GTZC_TZSC external memory x non-secure watermark register 2

(GTZC_TZSC_MPCWMxBNSR)

Address offset: 0x034 + 0x008 * (x-1), (x = 1 to 2)

In the debugger... it looks like its there... Here I set x=(1..3) for A&B

(gdb) set *0x50032430=0x11223344

(gdb) set *0x50032434=0x55667788

Hi Hedley,

Can you please tell me the version of SVD file you are using for stm32L5?

Thank you,

Hi Imen,

1.1

Tnx

Hi Hedley,

I did verify and today we have a more advansed version (v1.4) for the STM32L5 svd files with more fixes if you are interested.

Nevertheless regarding the point you raised, I can see your confusing about expecting via symmetry a B register at 0x44 like for GTZC_TZSC_MPCWM3ANSR.

In our SVD deliveries we have to be aligned with RM (RM0438) which according to description GTZC_TZSC is limited at @0x40.

I am going to raise this point internally basing on your Debug observation and hopefully come back to you soon with an answer.

Thank you for your feedbacks!
