MPC5674F Bootloader

[pyi285]

I want to ask something related to the code related to the MPC5634M chip bootloader, so I upload it.

Looking at the link or attached file below, can I know what the code in the SSD_driver file in the MPC5634M_bootloader file does? It's difficult to look at the data sheet.

I can remember that I already sent you the link to SSD drivers for MPC5674F. Then you can find user manual and API description here:

c:\Program Files (x86)\Freescale\Standard Software C90FL Driver v1.0.4\MPC5674_5676R\UM_C90FL_MM_SSD.pdf

The drivers are provided in pre-compiled form to avoid issues with compilers and also these files are usually used by flash programmers.

What it does - it just follows the procedures described in the reference manual like:

I don't have the link above. Could you please upload the pdf file you mentioned and explain in detail what the SSD does exactly?

Just install the drivers and you will find the manual in that folder:

알려주신 코드로 작성해본 결과 이런 결과가 나왔고, 함수를 사용할 수 없다고 하고, 소스를 사용할 수 없다고 합니다. 이것이 왜 그런지 아십니까?

If you jump into this function, you will see only pure asm code. As we already discussed, this driver is provided in pre-compiled form without source files. So, the debugger does not have details about the source. It's better to only step over these functions.
