LPC55S2x: impossible to upload firmware without ISP

[anton_hrabko]

Hi,

We have our own device with LPC55S28 rev B1. Our current hardware design doesn't support ISP pin & any possibilities to communicate with ISP, so we couldn't execute any ISP command.

We use MCUXpresso IDE v11.3.1 (ubuntu 18.04) + LPC-LINK2 CMSIS-DAP V5.361 (LPCXpresso55S28 rev A2) as debug probe. When CPU has a valid application, firmware uploading with crt_emu_cm_redlink works correctly.

Buf during development we had erased flash on LPC55S28 with crt_emu_cm_redlink and power off this chip. Then after reboot all flash commands of crt_emu_cm_redlink returns error Ef(34): Timed-out initializing flash. We try to use --rst or --vc, but have a same error. Is there something I'm missing? Is there another way to upload application to LPC55S28?

/usr/local/mcuxpressoide/ide/binaries/crt_emu_cm_redlink --flash-load-exec ./build_lpc55s28_Debug/starter/pks-starter.axf -p LPC55S28 --vendor=NXP --bootromstall 0x50000040 --flash-driver= -x ./tools/deps/lpc55s28/flash --flash-hashing 2>&1

Hi  @anton_hrabko 

I hope you are doing well, To narrow down this,  there are several different things that we could try:

• Erase the .launch debug files in your project and then try to debug.
• Try to program your application with the MCUXpresso GUI Flash Tool. More details on the IDE user guide.
•  Go to a new workspace and try to debug a blinky project. 
•  Update the LPC-Link2 FW using LPCscrypt:

             First Is good to check if you have the latest version of LPCscrypt, that can be found here

Try to update the LPC-Link 2 CMSIS firmware. The LPCXpresso EVB has a jumper to set the debug probe in DFU, set that jumper and use the LPCscrypt.

Also ,you can try to update the LPC-Link 2  with the CMSIS firmware. I use to do sanity test by using Segger's  J-Link Commander (usually it is installed on your PC when installing MCUXpresso) checking if the utility can connect with the MCU and see if an erase command works.

*If you require more details on how use LPCscrypt to program the LPC-Link2   let me know.

Let me know your findings

Regards!,
