Writing in User Block of Flash

Hello All

I am using RCM5600W module, and want to write on User block of flash. I can
write to the flash from the sample programs of Dynamic C 10.62, but when I
try to write in flash using the writeUserBlock() function in my own program,
my program stops, and debug window gets stuck. Is it due to the fact that my
program somehow utilize User Block of Flash memory? Kindly guide me how can
I write to flash inside my code. Thanks

Hi Waleed,

I use the User Block to save configuration data and using the RCM5450W.
Although not the same, it should be similar to the RCM5600W code wise.

Could you share the code you are using to write the block?

How big is the block you are writing?

Dave...

Hi Dave,

Thanks for your reply.
Right now I am trying to save data of very few bytes (3 to 4 bytes), which
is exactly same as mentioned in samples of Dynamic C 10.62 for User Block
Read/Write code. Interestingly, I can write and read the data from user
block at very start of my code, bu ast I am working on a program which saves
intermediate amount of data in memory and I need to save data in flash, so
when I call those functions inside my code, my debugger gets stuck, I would
have to recompile my code to start debugging.
