NameError: global name 'mode_verify' is not defined

[ShaneKent]

I've been running into a very strange situation when using this chflasher.exe to flash a CH559. It seems like any time I try to call a memset or memcpy or similar function that I come across this error:

packihx: read 373 lines, wrote 724: OK.

The binary is created correctly, but flashing process fails at the verify step. The binary is loaded properly without issue if I instead utilize the WCHISPTool to flash via Serial or USB connection.

I took the chflasher.py file in this repository and put it into my working directory. Doing that changed the error to this:

Perhaps this will add some more clarity on the issue.

gentle prod I'm also experiencing this problem in the same (or similar) circumstances whilst compiling and flashing code to a CH559.

From my very basic testing, I'm wondering if it's a file size issue? My code compiles with no issues with a reported file size of 11212 bytes. If I replace a 'DEBUG_OUT' command in USBHost.c (for example) with a 'printf' command, the file size goes up to 11303 and I get the reported errors:

I've tested and tested, and it seems a file size of up to 11267 bytes is fine, but 11268 (or more) causes the error. I've tested this by simply printing a string to serial using printf and increasing the size of the string until I found the cutoff between a successful compile and a failed one with the above error.
