Reading/Writing to File Msg "Disk was not ejected properly ... "

Hi

Every time I read/write to a file, I get an error "the disk was not ejected properly. If possible always eject ...",

Will getting the msg every time is okay or should I be doing something before/after reading/writing to a file?

Thanks

Hi Fatemah,

Yes, this is expected behaviour and fine.

As there are two masters on to the "disk" (the pc and the mbed), when the mbed wants to write to the filesystem it has to tell the pc the disk is ejected, then reinserted when finished. As the pc doesnt expect things to change on the disk behind its back, this ensures and activity by the mbed is seen by the pc, and also ensures they cant be trying to write at the same time.

On a windows machine, it will just accept this, whereas on mac it will get a little more upset, but it is fine/expected behaviour.

I too am unable to use my board, as my macbook won't upload the *.bin file. Is there any workaround to this or is the board just incompatible with macs? Is there any other way to get the program from my mac to the FRDM board? Thanks.

Simon,

In my case (MacBook Air/Lion OS), everything happens in the same way as Fatemah said, but the .bin file is not uploaded to the Freescale Freedom KL25Z board. So I am unable to use my board. :(

Any hint?

Thanks!
