The GPS parser looks for the VTG NMEA message in each NMEA frame received from the GPS receiver to determine the end of the frame (this isn't very good since VTG can be in different places depending on what receiver is used). If the message ID "VTG" or the new line at the end of the VTG message "\r\n" is corrupted, like from GSM interference on the UART lines, the parser won't find the message and the buffer is left unchanged since it doesn’t think the entire NMEA frame has been received yet. If the VTG message is corrupted for a few frames in a row then the buffer will fill up and is never cleared, and new frames won't be added to the buffer and processed.

Hi.
Please let me know any advice on this.
I have 5 days stucked on this, trying to set the A9G flashing enviroment. This has been a real pain because official site is outdated about software.
I downloaded your fies for windows:
[CSDTK42_Update2_18_7_27.7z]
[GPRS_C_SDK_V2129.zip]
I put them in C: root, using folder names:
CSDTK
GPRS_C_SDK
Later on CSDTK I run "config_env_admin" as administrator, which finisk OK.
Later on GPRS_C_SDK folder I open a POWER SHELL WINDOW and run "./build.bat app" which also finish OK.
I compiled the program call from DEMO folder which finished OK also.
Later on coolwatcher I select the flash Programmer as host_8955_flsh_spi32m_ramrun.lod
And finally select the compiled file, CALL (from demo folder): C:/GPRS_C_SDK/hex/call/call_B2129_debug.lod
But when I press the burn button (launch fastpf), I get several errors and the process stops:
I´m using Windows 11, a PROLIFIC cable and the latest driver taken from PROLIFIC page. The cable look fine when checked on Windows device manager.
Any idea why this error ?
