firware doesn't run after USB boot

Hello everyone,

hope Monday is treating you well.
I am having a hard time getting the USB ISP to work on the lpc1549 LPCXpresso board. This is what I do:
[list]
[*]generate the .bin file as described here
[*]plug the board from the target socket while pressing the ISP0 button in order to recall the USB bootloader
[*]a driver called CRP_DISABLD shows up: I delete the firmware.bin file inside it (it takes up all the space) and then copy my own .bin file
[*]after a power cycle (unplug&plug) nothing really happens, and rebooting with both ISP asserted high falls back to the USB bootloader
[/list]

ps: in case it'd make any difference, i'm using a Linux machine.

unfortunately not, here's my post-build steps:

arm-none-eabi-size "${BuildArtifactFileName}"
arm-none-eabi-objcopy -v -O binary "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin"
checksum -p ${TargetChip} -d "${BuildArtifactFileBaseName}.bin"

(it's basically the default stuff)

Are you sure your code is working?

Is it working if you flash it via SWD? Or UART? Or CAN?

I can successfully upload and run it through SWD, moreover I had no luck with the blinker example either :(

Could be useful to post the project...

Did you unmount it before unplugging, to make sure the data was actually written?

@R2D2: I tried with the freeRTOS blinky example, 100% vanilla, only change was enabling post build steps

@starblue: whenever i do i get an error message on linux stating

Quote:

Error ejecting /dev/sdc: Command-line `eject "/dev/sdc"' exited with non-zero exit status 1: eject: unable to eject, last error: Invalid argument

Did you compare the Flash bin-file with your project bin-file?

I'm not sure i understand what you mean by compare :~
when I reconnect the board after copying the bin file, a new file called firware.bin shows upand it has the same size as always (it fills up all the memory, that is)

Compare these little funny bytes :O

If there's no difference between the flash file and your original project bin file, there's no problem with flashing your MCU and you can start to check the hardware...

Hi miccio,
As suggested by other could you please check below?
1) Flash binary using SWD, remove the SWD, reset the board and check if firmware works.
2) If step one is okay flash the firmware using SWD and see the result.
3) if step2 is not correct, compare the binaries as suggested by R2D2.

If step1 is not okay, could you please check if you are using a reset pin as GPIO output?
