Hello,

 

I am using Coldfire microcontroller MCF5213 to download bootloader firmware serially(using EZ port) in to another coldfire board .

I am facing following problem:

First : I am able to  Write 256 bytes of data using PAGE_PROGRAM COMMAND and then verify it using FAST_READ COMMAND which worked fine.

When i send the next 256 Byte data using page program command it is getting programmed which i could make out when i read EZ port STATUS REGISTER ,but when i verify the sent data using FAST_READ COMMAND the data is seen corrupted.

 

Secondly:

After my first 256 byte is send and verified.when i send WRITEENABLE command to EZ port and then read the EzPort STATUS_REGISTER  it shows that the WEN(Write Enable)bit in status register is not set............................

 

 

 

Kindly Help..................I need to dump 2K bytes into the other coldfire board..................

Pls provide the example source code ............

 

Regards

Angel
