Hi All I’m getting the below error with a blank sketch with empty setup and loop functions. I have the RTL8735B AMB82 Mini board > Compilation error: fork/exec C:\Users\advic\AppData\Local\Arduino15\packages\realtek\tools\ameba\_pro2\_toolchain\1.0.1-p1/bin/arm-none-eabi-ar.exe: The parameter is incorrect. Can anyone point me in the right direction with this compilation error Thanks ---

Error occurred while unzipping sdk toolchain. Suspected that the toolchain was not download correctly. Maybe you can try to erase folder under path: `C:\Users\advic\AppData\Local\Arduino15\packages\realtek` and download the AMB82-MINI sdk from Arduino IDE again. Thank you ---

Hi thanks I deleted the Realtek folder, rebooted computer, and reinstalled ameba into board manager, this was the install log > Downloading packages > realtek:ameba\_pro2\_toolchain@1.0.1-p1 > realtek:ameba\_pro2\_toolchain2@1.0.1-p2 > [realtek:ameba\_pro2\_tools@1.2.9.1](mailto:realtek:ameba_pro2_tools@1.2.9.1) > realtek:AmebaPro2@4.0.4 > Installing realtek:ameba\_pro2\_toolchain@1.0.1-p1 > Configuring tool. > realtek:ameba\_pro2\_toolchain@1.0.1-p1 installed > Installing realtek:ameba\_pro2\_toolchain2@1.0.1-p2 > Configuring tool. > realtek:ameba\_pro2\_toolchain2@1.0.1-p2 installed > Installing [realtek:ameba\_pro2\_tools@1.2.9.1](mailto:realtek:ameba_pro2_tools@1.2.9.1) > Configuring tool. > [realtek:ameba\_pro2\_tools@1.2.9.1](mailto:realtek:ameba_pro2_tools@1.2.9.1) installed > Installing platform realtek:AmebaPro2@4.0.4 > Configuring platform. > Platform realtek:AmebaPro2@4.0.4 installed Then closed Arduino IDE and relaunched it And below is the current compilation error for the blank setup and loop file > exit status 0xc0000005 > Compilation error: exit status 0xc0000005 Your suggestion very much appreciated ---

Hi Here is another clue. I’ve tried to compile with Arduino 1.8.16 and got this compile error with a blank setup and loop test file > exec: “/bin/arm-none-eabi-g++”: file does not exist > Error compiling for board AMB82-MINI. Hope we can sort this out, I’m stuck ---

Hi @Jacques_Mulder , Error `0xC0000005` in SDK-v4.0.4 is caused by stack overflow in the ino\_validation.exe or nn\_model\_update.exe tools running on some of the Windows machines. Now this bug has been fixed via: [Arduino tool update (#144) · ambiot/ambpro2\_arduino@856abb8 · GitHub](https://github.com/ambiot/ambpro2_arduino/commit/856abb837b36fe1f749c0ded51032c8af5ac6f09). Currently the fix is on the `/dev` branch, if you wish to continuing using released version `v4.0.4` for your development, you many download the windows executables tools and replace them under `C:\Users\advic\AppData\Local\Arduino15\packages\realtek\tools\ameba_pro2_tools\1.x.x` upon reinstall your Arduino SDK environment. > Note: > In order to set up a clear environment without causing any compilation issues from toolchain folder, I suggest to delete everything under `C:\Users\advic\AppData\Local\Arduino15\packages\realtek\tools` and `C:\Users\advic\AppData\Local\Arduino15\packages\realtek\hardware` before download a new SDK from Arduino IDE. Hope it could help. Thanks. ---

Hi, Ok great, so do you mean this is a known issue with 4.0.4 Because in that case it might be easier just to install earlier version instead of trying to fix 4.0.4 ---

Hi, Yes. Alternatively, you may temporarily use the link provided below to install /dev branch Arduino sdk: [https://github.com/ambiot/ambpro2\_arduino/raw/dev/Arduino\_package/package\_realtek\_amebapro2\_early\_index.json](https://github.com/ambiot/ambpro2_arduino/raw/dev/Arduino_package/package_realtek_amebapro2_early_index.json) This issue has been fixed on /dev. Thanks. ---

Hi, Please do not revert back to old version since the tools in v4.0.0 might not be fully supported yet. Thanks
