s32g-vnp-rdb2 - Errror when uploading sja1110_uc and using gPTP

[nicolasespla93]

Hi,

I'm trying to use the gPTP stack for SJ1110 and S32G-VNP-RDB2, however, when I upload a configuration that includes the gPTP stack I get the following issue:

I used "switch_config_s32g_vnp_rdb" as base project, then I updated the configuration to add the gPTP stack following the instructions in  "SJA1110 GPTP CONFIGURATION" presentation, then I compiled the updated code and sent the configuration to the switch. could you help me to understand why I'm getting the error message?

Note: If I only include the gPTP stack as part of the configuration and I compile it (the gptp stack is not used in the user application) the issue also happens

My board is: S32G-VNP-RDB2

PFE Driver: 1.0

Hi @nicolasespla93 ,

I had the same problem when I added gPTP to my project.

How did you solve this problem?

Thanks, 

Ethan.

Hi @Ethan_L 

I apologize about the delay on my answer, if you are still facing this problem this is what I have.

i was told that whenever you integrate the gPTP stack to de configuration file, the file is padded with 0x00, this padding is not included as part of the file size in the file headers. This provokes that the driver thinks that the file has already been transferred even when the padded data is still being transferred(the driver uses the length defined in the header, while Linux transfers the whole file), as the transference has not actually end, it causes a data corruption and for this reason we see this error message.

to solve this, a work around was provided.you need to manually remove the padded data at the end of the file (scroll to the end of the file, and remove the Last part where there are only 0x00) after doing this the file is successfully transferred and verified!

best regards

Hi @Daniel-Aguirre ,

I also want to know if there is a way to solve this issue other than by manually deleting.

Thanks.

Hi Daniel,

It seems a known issue in NXP, will you fix this issue in the future?

Thanks.
