Hello everyone, I am working on MCUxpresso and using LPC1769 controller. I am done with Led blinking in MCUxpresso. I have used flash magic to flash the hex file in controller using usb to ttl. But I faced a hex file issue while doing this project. So I thought I should share this with everyone who are facing the same issue. After compiling only .axf was getting created. For creating .hex file ,you need to do following settings:
1)Go to properties---> C/C++ Build --->Settings ---> Build Steps
Now in post build steps :
Change
arm-none-eabi-size "${BuildArtifactFileName}"
# arm-none-eabi-objcopy -v -O binary "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin"
# checksum -p ${TargetChip} -d "${BuildArtifactFileBaseName}.bin
to
arm-none-eabi-size "${BuildArtifactFileName}"
# arm-none-eabi-objcopy -v -O hex "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.hex"
# checksum -p ${TargetChip} -d "${BuildArtifactFileBaseName}.hex"
2) After doing step 1, please check if axf is selected in Artifact extension as shown below:
3)For creating hex file go to Debug-->.axf file-->Right Click-->Binary Utilities-->Create hex. Now you are ready to flash!
Also kindly check this article:MCUXpresso IDE: Creating Binary Files (S-Record, Intel Hex, Binary)
After doing these settings I got the hex file and finally it worked!!
