HI, I am using 56801 with limited memory space and want to save constants into a certain data flash area while flash programming. I am able to do it using the sdk, but unfortunately this takes up to much space. Does anyone have an example of writing to the data flash without using the sdk? Thanks.

Hi Paul, Attached is an example of how to program the data flash without using the SDK driver. This project was written by Daniel Malik from Motorola.

Fabio, Yahoo no longer distributes attachments nor stores them on their servers, can you please upload the file to the files section of the message board or provide a link to its location.

On second thought I think maybe I didn't get it file because I just get a daily digest. I'm going to switch to individual e-mails and maybe I'll get them in the future. Thanks to Fabio and every one who did get the file and sent it to me, I now have pleanty of copies.

Okay Fabio, I'm using your routine for programming flash and it's working great. Problem is when I try to erase the board hangs. If I'm in debug mode sometimes the program will break on an unhanded interrupt. If I single step through the erase function it works great. My gut feeling is that I'm out of stack space, but when do a dflash_program call I'm using more stack space (due to my parse routine) so I'm pretty sure that's not the problem. Changes I'm made: I changed the var names to use the arch.h naming convention. I added setting the ControlReg back to zero (though I don't think it's needed due to the while loop just above, the UM said to do so). Jacob --------- void dflash_erase(unsigned int addr) { unsigned int readsyscntl; ArchIO.DataFlash.IntSourceReg = 0; ArchIO.DataFlash.ProgramReg = 0; ArchIO.DataFlash.EraseReg = 0; ArchIO.DataFlash.ControlReg = 0; while ((readsyscntl = ArchIO.DataFlash.ControlReg) & 0x8000 ); ArchIO.DataFlash.EraseReg = 0x4000 + ( ( addr >> 8) & 0x007f); *(unsigned int *)addr=0; while ((readsyscntl = ArchIO.DataFlash.ControlReg) & 0x8000 ); ArchIO.DataFlash.EraseReg = 0; ArchIO.DataFlash.ControlReg = 0; } --- In , Estevam Fabio-R49496 <Fabio.Estevam@m...> wrote: > Hi Paul, > > Attached is an example of how to program the data flash without using the SDK driver.

I think I found my answer in some of Art Johnsons's old posts.
I'm not sure what's being accesed, but when I disable interrupts prior to erasing the flash every thing works great. So I'm assuming that there is some constant data that CW is putting into xFlash that is being accessed in one of my interrupts, and that this access durring the erase is what was casing my program to crash. This may also explain why when I single stepped through the erase code the program didn't crash.

Fabio, I am using the SDK quad timer. I think that is pretty much the only interrupt I am using that would fire during the flash erase. I think I was just getting lucky that programming was working, takes less time so I guess less likely to have an interrupt during the write. I also have an array of that is being accessed during the interrupt, but suspect that it should be in ram because it's not const. I'll check it out.

If I remember correctly SDK places some data in data flash and maybe this can be the cause for the problem you have seen.
