LPC55S2x: impossible to upload firmware without ISP

anton_hrabko — Wed, 21 Apr 2021 10:15:56 GMT

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?

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!,

Diego
