Flash LPC55s36 with OpenOCD

Hi,

I'm trying to flash a LPC55s36 MCU using OpenOCD, but it seems like the reset step is failing and I'm not sure where to go from there.

OpenOCD does not support the board yet, but there is a pull request (https://review.openocd.org/c/openocd/+/6800?tab=comments) which adds support for a similar board. So I have taken that config and adapted to LPC55s36.

source [find target/swj-dp.tcl] if { [info exists CHIPNAME] } { set _CHIPNAME $CHIPNAME } else { set _CHIPNAME lpc55s36 } # # JTAG mode TAP # if { [info exists M33_JTAG_TAPID] } { set _JTAG_TAPID $M33_JTAG_TAPID } else { set _JTAG_TAPID 0x4ba00477 } # # SWD mode TAP # if { [info exists M33_SWD_TAPID] } { set _SWD_TAPID $M33_SWD_TAPID } else { # set _SWD_TAPID 0x2ba01477 set _SWD_TAPID 0x0be12477 #set _SWD_TAPID 0x410fd214 } if { [using_jtag] } { set _CPUTAPID $_JTAG_TAPID } { set _CPUTAPID $_SWD_TAPID } swj_newdap $_CHIPNAME m4 -irlen 4 -ircapture 0x1 -irmask 0xf \ -expected-id $_CPUTAPID dap create $_CHIPNAME.m4.dap -chain-position $_CHIPNAME.m4 target create $_CHIPNAME.m4 cortex_m -dap $_CHIPNAME.m4.dap # LPCSSS36-EVK has 112 KB SRAM if { [info exists WORKAREASIZE] } { set _WORKAREASIZE $WORKAREASIZE } else { set _WORKAREASIZE 0x1C000 } $_CHIPNAME.m4 configure -work-area-phys 0x20000000 \ -work-area-size $_WORKAREASIZE -work-area-backup 0 #if {![using_hla]} { # # on this CPU we should use VECTRESET to perform a soft reset and # # manually reset the periphery # # SRST or SYSRESETREQ disable the debug interface for the time of # # the reset and will not fit our requirements for a consistent debug # # session # cortex_m reset_config vectreset #} cortex_m reset_config sysresetreq adapter speed 400 #adapter srst delay 100 #adapter srst pulse_width 100 #reset_config srst_nogate # reset_config srst_only

Then running with:

sudo openocd -d -f interface/cmsis-dap.cfg -f lpc55s36.cfg -c "program [FILE] verify reset exit"

And eventually getting:

Has anyone managed to flash this board w/ OpenOCD? Otherwise, what are the alternatives given that I need to be able to programatically do it from a ARM32 Linux machine using SWD.

Hi,

For the programming on-chip flash of LPC55s36, the ROM provides the API function to program flash.

Pls download the reference manual of LPC55S36 from the link:

https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/general-purpose-mcus/lpc5500-arm-cortex-m33/lpc553x-s3x-advanced-analog-armcortex-m33-based-mcu-family:LPC553x

Refer to section 28.2.1 ROM API structure.

BTW, pls download SDK package from the link:

https://mcuxpresso.nxp.com/en/welcome

There is flash operation example

Hope it can help you
