I’m so worried because initially I put these 3 binary files in the same folder with ambd_flash_tool.
But in case of erase or flash fail this SW rewrites these files with 0xFF content. And in subsequent use it ofcourse will flash all content to RTL chip. I remember that I made path error on first use and then made seweral erase/flash cycles. So, maybe important settings were lost and now the FW works not as expected.
