Can not program KW36 Dflash

[JingsaiLu]

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:

@flit Do you have any idea about this issue? Does pyocd support the feature to change flash algo dynamically according to different programming address?

Really sorry for the slow reply! Yes, pyOCD can have a different flash algo for each flash region. Everything you are describing should work.

There is obviously some bug when programming an image that crosses flash region boundaries. I thought I had fixed that a while back. What version of pyOCD are you using?

Could you create a pull request with your changes? Or attach a patch file to this issue. Also please attach the test image binary that you are using.
