HSE development

[ALXY_WANG]

我在官网下载的HSE_FW_S32K344_0_2_40_0进行HSE FW安装，首先在0x1B000000写入8bytes的随机数后修改内存分区导入AB_swap的PINK文件，在用PE导入官网下载的OTA_demo文件就无法导入了，后面PE无法对MCU导入任何文件，可以指导一下流程有何错误吗

Hi @ALXY_WANG 

once HSE firmware is installed, it's necessary to change programming algorithm for Pemicro debugger.See please attached screenshot. The reason is that HSE FW allocates part of flash which can be accessed exclusively by HSE only. See tables 180, 181 and 182 in the S32K3 reference manual for details. If standard programming algorithm is used, it tries to erase those areas which is not possible after HSE FW installation.
