elbc programing for p4080

[monalihaware]

i have p4080. want to program NOR flash on the board connected to gpcm.

how do i send the command sequence like '555' and 'aa' on the adrress and data lines of the gpcm. i dont find any registers in gpcm to send a particular address/data on the memory connected to gpcm,As these said addresses are very much required for the command sequence of NOR flash

When you write a value to the address window configured for the chipselect (with a LAW mapping the region to eLBC), that will cause the address (based on offset into the window) and data lines to be driven appropriately.

You should configure Enhanced Local Bus Controller (eLBC) for your NOR Flash and use read/write operations for this NOR Flash.

See the following page:

Usually customers use a tool for Flash programming. Look at NXP CodeWarrior Development system:

CodeWarrior includes Flash Programmer. It support most NOR Flashes. Evaluation version of CodeWarrior can be used during 30 days. There are no other limitation for using evaluation version.

Use CodeWarrior for NOR Flash programming on your board.

Have a great day,
Pavel
