Change the DDR2 chips of mpc8309twr development board

[lijiankun198]

Hello everyone，

   In our project, I customed a board base on mpc8309twr development board. Because the Hynix H5PS5162FFR DDR2 chip on mpc8309twr development board does not produce now, we need change the chip. We choose the Micron MT47H32M16 to replace the H5PS5162FFR (work in 32bits). But the uboot can not work now. So, we want to use the CodeWarrior software program the uboot into board through CodeWarrior Tap. I changed the ddr configuration part of 8309TWR_init_core.tcl file , but it still does not work.

The CodeWarrior software print :

Downloading Flash Device Driver ...
Reading flash ID .......
Error: The algorithm was not able to run on the target or the flash is not configured properly.
Error: Getting flash ID failed
Error: The algorithm was not able to run on the target or the flash is not configured properly.

How to configure the ddr configuration part of 8309TWR_init_core.tcl file ?

Any help will be appreciated！

Thank you.

Sorry, we do not offer ready-to-use target initialization files for any possible customer configurations, because it is not possible to test all customer configurations here, in our labs. Instead, we offer a full set of documentation to let our customers to develop their own custom configurations. To create target initialization file for your custom DDR2 memory configuration, I recommend using the following documents:
