Hi Andy,

Although i cleaned the ground from noise, sometimes i keep receiving errors on connection.

I have searched in the dll functions and used the fm_raw_connect(..), and it always passed successfully.

But i couldn't erase or program the device - Can i use the fm_erase(..) after a raw_connect?.

what is the difference between the fm_connect and the fm_raw_connect functions?

and is there a way to program/erase the device with these funrtions? (raw_transmit/receive)

Thanks in advance,
Daniel

Hi Andy,

Thank you for your quick reply. The problem was in noisy ground on the board..

Hi,

The answer i'm receiving is: "Unable to communicate. Failed to autobaud". and not configuration..

Thanks in advance,

Hi,

I'm having a board with 20 LPC925 devices, each LPC925 connected through a MCP2200 (USB to rs232 converter).

I'm having problem to connect to any device (with Flash Magic or my program). The answers i keep getting is: "Unable to communicate. (configuration)".

I removed all the LPC devices and communicate with only one - and it is working.

Is there any limit using multiple devices with Flash Magic or FM_functions? (fm_connect, erase, and program) or do i need to use another function?

Also, I have noticed that in device manager i see all my COMs starting with "COM56" .. to "COM76", but in the Flash Magic the COMs starting with "COM1" to "COM32".

I'm using win XP, and Flash Magic 6.50.2644.

Thanks in advance,
Daniel

ok, i will implement the reset by hardware.

Thank you Andy for your help!

Hi Andy,

Thank you for your reply.

Just to be sure, If i don't have the supporting hardware on the board (Its a medical device so its forbidden), i can't reset the device using sofware?

Is there any way to change the bootloader to reset the device?

Thanks in advance,
Daniel

i tried the following line code:
presults = fm_reset(FM_RESET,0x00000000,0);

and i keep getting "Device does not support operation. (reset)"

Thanks,
Daniel

Hi,

I'm using the flash magic dll functions, LPC925 device, and need to reset the device after programming.

Can anyone help me with the fm_reset function arguments? (didn't find any documetation..)

Thanks in advance,
