Can not program KW36 Dflash

I have a binary which size is larger than 256kB, so need to program both Pflash and Dflash.
The KW36 memory map is as below image.

I try to use pyocd flash command to program my binary with below command:
pyocd flash -b 0251000041114e45002d3007bcf900209e51000097969900 -a 0x00000000 "D:\mcu\wireless_uart_frdmkw.bin"
but it report an error as below:

So, I check the flash algo file at pyocd\target\builtin\target_MKW36Z512xxx4.py
and find something is not aligned with MCU user manual, marked as red:

I want to fix this issue, so I try to generate flash algo for alisa flash and D flash from FLM files, and modify this target_MKW36Z512xxx4.py script as bolow:

I assign different flash algo for Pflahs / alisa Dflash and Dflash from 3 FLMs in Kinetis_KWxx_DFP 1.9.
I try to program this 3 part flash with a small image seperately with different target address, like;
pyocd flash -b 0251000041114e45002d3007bcf900209e51000097969900 -a 0x10000000 "hello.bin
pyocd flash -b 0251000041114e45002d3007bcf900209e51000097969900 -a 0x00004000 "hello.bin
pyocd flash -b 0251000041114e45002d3007bcf900209e51000097969900 -a 0x00000000 "hello.bin
They are all OK in flashing binary progress as below:

But when I try to program my big binary(larger than 256kB), it still report an error after a while as below:

Start with pyocd/target/builtin/target_MKW36Z512xxx4.py and compare its flash regions with the KW36 memory map and the three FLM files mentioned in the issue. Reproduce the separate small-image commands, then test the larger-than-256kB binary across Pflash and Dflash. Done means the complete binary programs successfully without the reported error.
