spi eeprom burning problem for C55

metusa

Hi all,

I have problem related to burning eeprom. I have 64KB spi eeprom on which I flashed application program. It is programmed with no error.

But when I replace it with 1Mbit(128KB) one, I get the following error;

SPI EEPROM...

Writing data to device...

Opening D:\CSL_AUDIO_DRIVER.bin...

Input file opened

WRITE ERROR! at 0x0000

Wrote 0x09aa Read 0x00ff

- I am using C5505. I know it should support 16 bit and 24 bit spi flash. Doesn't it?

- Or, what can be the reason?

I use M95M01-RMN6TP eeprom.

Thanks,

Hi;

The C5505 does support 24bit SPI flash memory. Which programmer do you use? And where did you get it? I think you need to get the latest programmer for C5505.

Here is the detail info for how to program the C5515/C5505:

Hi Wen,

I have tried programmer_C5515_EVM.out as you suggested, but I get write error still. I downloaded programmer from http://support.spectrumdigital.com/boards/evm5505/revd/

and follow the instructions on text file. There was no problem for 64KB spi eeprom.

I recommend that you grab the data sheets for both EEPROM chips, the 16-bit that works and the 24-bit that doesn't. Then compare the Erase and Write commands to see if they are implemented differently or if there is some other unique mode or setting for the one that isn't working.

I suggest this because I am working with an SPI Flash that has 264 bytes per page until you burn a one-time fuse that sets it to 256 bytes per page. In my application, I prefer to retain the extra capacity with 264 bytes per page, but I imagine that software other than my own programming routines might not be compatible.

Hi Wen

Can I have the source code of the programmer.out file? Because C5505 programmer support 16bit addressing, I need 24bit. One more thing, I tried to program by using C5515 evm.out, it failed. I see no signals on scope. Where can I download 24bit programmer for C5505?

We are in the legal process to release the source code.

Hi Steve

Approximately, when it will be available? I need urgent, please.

Thanks...

If you need this functionality urgently, then I suggest that you develop it. All you need is the data sheet for your memory chip and knowledge of C5000 programming. The commands are quite simple.

0508.SPI_EEPROM_TEST.rar

This is SPI EEPROM and SPI FLASH PROGRAMMER CCS V5 project. Code Composer Studio V5 is neccessary.

It's support for 32Kbit, 64Kbit, 128Kbit to 1MBIT, 4Mbit memory device.

Change definations in config.h according to your memory device. (16 bit or 24 bit)

Take a easy...
