C90 SSD Driver

Hi,

I am using MPC5634 MCU Flash module for bootloader, but there are two versions:

for example :

1. BlankCheck.c

vertion 1:

/* Total Data Size = 436 bytes */

One vertion is function,the other is array.Is there any different between them?

Also you can see attachment files.

Hi,

use the C-array drivers. The source codes are provided only for reference. The SSD drivers are provided in pre-compiled form to avoid possible issues caused by different compilers.

The latest driver for MPC5634M is this one:

http://www.nxp.com/files/soft_dev_tools/software/device_drivers/MPC56XX_C90LC_JDP_SSD_100_DEVD.exe

Examples are included in the package.

You can also take a look at this bootloader for MPC5634M - SDD flash drivers are used there:

@Lukas Zadrapa ,Thank you very much.

I want to use first vertion-- f

OK, but please notice that we do not support customers who use the source files directly...
