RA6m3 OTA boot to APP

以下是跳转函数

void execute_user_code(uint32_t address)
{

main_fnptr *p_jump_to_app; // Function pointer main that will be used to jump to application

请问是参考下面的文档做的OTA吗？

RA6 Secure Bootloader Using MCUboot and Internal Code Flash (renesas.cn)

RA6 Secure Bootloader Using MCUboot and Internal Code Flash - Sample Code | Renesas

请问一下，需要请教以下二个问题：

1、IC使用的是R7FA6M3AH，使用J-LINK烧录，单片机程序TFT屏等不能正常使用，反而选择R7FS5D97C烧录完成后，TFT屏等程序可以正常使用，技术支持回复是：JLINK厂家在J Flash Lite里面并没有适配R7FA6M3AH的QSPI，而R7FS5D97C有？这个是这样的吗？

问题2：boot跳转到APP成功后，一直不亮屏，直接跑到xPortStartScheduler-》  prvPortStartFirstTask就出现硬件异常（Default_Handler）。而使用J-LINK烧录时，程序能够正常运行。这是为何？

进入APP后，是否需要重定位中断向量表？如果需要，如何设置？麻烦指定一下，谢谢！

基于MCUboot的bootloader不用单独处理，按相关应用笔记的配置过程进行配置就可以了

对于前述的两个问题：

1. 可以使用RFP （Renesas Flash Programmer）进行烧写

R7FS5D97C和R7FA6M3AH是两款不同的产品

2. 你的意思是指使用J-LINK烧写APP工作正常，而合并boot+APP就工作不正常了？
