can't program bootloader code by nrfjprog tool

Hi Nordic, we need to modify bootloader code base on your dfu example. Now We meet a problem that we can't program it by clicking icon "Load" on keil comile project. report error as below:

//-----------------------------------------------------------------------
Programing device.
ERROR: JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
nrfjprog.exe --program "D:\project\SPW07A\Bootloader_Code\examples\dfu\bootloader\pca10040\dual_bank_ble_s132\arm5_no_packs\_build\nrf52832_xxaa_s132.HEX" -f NRF52  --chiperase --log

according to error's hint, I add --log after --program "#H" -f NRF52 --chiperase --log and get the log text. pls refer the attached file.JLinkARM.log.txt but i can't find the reason. if we use the same project to program it on EVB PCA10040, it is ok. why ? Is the different between the EVB PCA10040 's JLINK and our JLINK cause the issue? how to fix it? Thanks.

Could you try to first erase the erase the chip

nrfjprog -f nrf52 -e

and then flash the SoftDevice and the bootloader using

nrfjprog -f --program <name of hex file>.hex

usee the cmd according to your info .first erase the chip that is ok. but program it that still fail and report the same error. the info is as below:

1.erase is ok: D:\project\VOX02_OLED\code\examples\ble_peripheral\nrf5-ble-tutorial-service\pca 10040\s132\arm5_no_packs>nrfjprog -f nrf52 -e Erasing code and UICR flash areas. Applying system reset.

2.then program failed: Parsing hex file. Reading flash area to program to guarantee it is erased. Checking that the area to write is not protected. Programing device. ERROR: JLinkARM DLL reported an error. Try again. If error condition ERROR: persists, run the same command again with argument --log, contact Nordic ERROR: Semiconductor and provide the generated log.log file to them.

Could you try to recover the chip, i.e.

nrfjprog -f nrf52 --recover

and then try to program it?
