On the calculator... #3

After installing the SDK; I have this error with this command make epsilon_flash. It was from the directory that was made with the repo.

LD epsilon.elf ion/src/device/stack.cpp:4:21: warning: type of '_stack_end' does not match original declaration [-Wlto-type-mismatch] 4 | extern const void * _stack_end; | ^ ion/src/device/usb/dfu_relocated.cpp:6:13: note: '_stack_end' was previously declared here 6 | extern char _stack_end; | ^ OBJCOPY epsilon.bin arm-none-eabi-objcopy: 'epsilon.elf': No such file make: *** [epsilon.bin] Error 1

Re-running the command gives make: *** [epsilon.bin] Error 1

Can you try with make build/device/epsilon_flash ?

UPDATE: I tried it with the calculator in recovery mode... and it worked :-) Now some finetuning with the Rasberry Pi :-) thanks! thanks

Can you try with make build/device/epsilon_flash ?

I've followed the tutorial to the letter, when I run the application on the calculator it just gives a gray screen. I do have a SSH connection with the Pi. Any tips on troubleshooting?

I think you should check if the kernel module is loaded, and fbcp is working. Without fbcp, you can also just try to write some random data to /dev/fb1 to check if something is displayed on the screen.

I have a known working sd card image for a Raspberry Pi Zero. It is a little bit old, but it may be helpful to test for a hardware problem : https://transfer.sh/1LEyEjM/2019-07-10-raspbian-buster-full-rpi-trimmed.lzma (sha256 : 4c046ba8b47868805f64e6316b442cad20487b51216ef4b5e74c184573f1148a) With this image, booting is sometimes very slow, more than one minute.

thanks! I've downloaded the file... but I have no experience with lzma-files ... I've been Googling the last few days, but no where closer to extract the file to a memory card,

From linux, you should run something like this : xzcat 2019-07-10-raspbian-buster-full-rpi-trimmed.lzma > /dev/mmcblk0 (/dev/mmcblk0 being your SD card). From windows, I guess you can extract the raw image using 7zip, then writing it to the SD card the same way as an "official" raspberry pi image.
