Hi Daniel,
Thanks for your reply, 'march-s32' is an ARM arch in U-boot of yocto release/bsp35.0. As you know I want to use the SPL feature of U-boot on my s32g rdb3 in order to automatically switch to a safe U-boot when SPL loads a bad U-boot image. I have done this successfully on i.mx6, but the s32grdb3 U-boot seems does not support SPL feature. Does the ATF meet my requirement?
Thanks and Best Regards,
Minghu
I used SPL + watchdog to implement that. If a broken U-boot is loaded the watchdog will trigger a timeout reset and then SPL loads the safe U-boot.
Hi,
Could you elaborate more on what you are referring to u-boot SPL? Also, we cannot find anything related to a march-s32 based board.
As for RDB3, you can look into what it is available under the BSP for S32 Microcontrollers and Processors product page (link: BSP for S32 MCUs and Processors | NXP Semiconductors). At this moment, only the S32G2 processor is shown on the available devices (regarding S32G family), but should give you a general idea of what it is available on the S32G family.
Please, let us know.
Hi,
We have the following update:
"Linux BSP does not include this functionality as this is the role of BL2 stage from ATF (SPL - Secondary program loader. Sets up SDRAM and loads U-Boot proper. It may also load other firmware components.)"
Please, let us know.
