Update IVT in RAM failed?

[bookar]

I am working on S32G m7 core, with S32DS。 

to satrtup from SD card, I modified the .ld file acording to <S32G-GOLDBOX-SW-UG> page 19, and then I found that the uart interrupt handler dont sevice correctly。

It seem's that the IntCtrl_Ip_InstallHandler interface dont install the handler correctly, and the default undefined_handler will be called, instead of the expected handler that installed by IntCtrl_Ip_InstallHandler。

Is that caused by cache?

Hi, 

Could you provide us with what S32DS/RTD version you are working with? Also, are you working with any NXP board?

Following the S32G-GOLDBOX-SW-UG, did you create the example it is provided in there? Did it work?

Have you tried with other examples? The behavior is the same?

Please, let us know.

Hi,

Thanks for your reply.

I,m working on GoldBOX, with S32DS version 3.4, RTD  version 3.0.2, and SPD version 1.9.0。

I didnt try other project with this ld file, I will try later.

Forgot to mention, with the "int_sram_no_cacheable" area start from 0x34500000 in ld file, everything seem,s to be OK。

Hi,

Thanks for your feedback.

Just to verify, if "int_sram_no_cachable" is set as the default (ORIGIN=0x35000000, LENGTH=00100000), you see no problem?

Please, let us know.

[bookar]

yes.

if "int_sram_no_cachable" is set as the default (ORIGIN=0x35000000, LENGTH=00100000), there is no problem。the uart interrupt handler installed with IntCtrl_Ip_InstallHandler works well。

Correction: The default of "int_sram_no_cachable" is (ORIGIN=0x34500000, LENGTH=00100000)。

Hi,

Thanks for the correction. We were wrong in the value, as you noted.
