Hi @Rob_t
Firstly I think that did you mean S32K358.
Is there IAR support for this chip/board? IAR offers broad NXP coverage with support for Kinetis, LPC, Vybrid, i.MX and S32K, as well as S08.
Is there J-Link support for this chip/board? J-Link offers support to S32K3 devices, specifically the ones listed in the below link.
Supported Devices - J-Link - NXP - S32K3
Is there a specific SDK/BSP for this board? The available software that supports S32K358 is the S32K3 Real-Time Drivers Version 3.0.0 (released on March 31) and onwards. You can download it from S32K3 Standard Software -> Automotive SW - S32K3/S32M27x - Real-Time Drivers for Cortex-M.
As the S32K358 is still not a mass-market device, not all the information is public. I suggest you contact your NXP representative for further information on this part.
Note: the first two questions are generalized for the S32K3, because of the reason previously mentioned.
