Hi

 

Am having a bad day -- can you point out where I might be going wrong

 

I have a project -- using 548 LCD screen -- build the project -- runs okay

I have settings using LDF with -- access external memory

and options using external memory

 

I then switch over to generating a loader

    QUESTION 1

    I presume I need a 16 bit width build

 

I then disconnect VDSP from the board, power down and power up

Reconnect VDSP and go and access the 548 loader

     I load the driver and load my ldr

    QUESTION 2

    I presume that there is only one driver, so that I can't make a mistake there

 

I then program the flash

     There are a number of large images that are hard coded so this takes a long time

 

I then disconnect from VDSP -- remove the JTAG and power down and power up

 

Not working is something I could handle -- but being totally ignored by the 548 is to much for my shattered ego

 

Iwas totally ignored, with the system booting up into the standard power up test showing  the 3 blackfin images

 

Any suggestions to solve my mistake would be apprecaited

 

Question 3 -- it is an older 548 board -- does that have any impact

 

Thanks

Mike Smith
