S32G Serial Boot A53 for Image Burning

 

      S32G just support serial download a M7 image to run by internal rom codes, our S32G DS IDE have a flash tools to use this feature to burn the image to external device. So current image burn method will divide into 2 step:

1: burn a uboot into the external device by S32G DS flash tools.

2: reboot the codes with uboot and run with network to burn the linux image into external device.

     which need two working place on manufacture line, and customer wish to have a one time on-line tools, which means we need use serial port to boot uboot directly but S32G rom codes do not support it.

      We have a reference tools of S32V but which IP difference is big between on S32V and S32G, So we can not reuse it and have to develop a new one.

      The development working include:
