Hello,

I’m trying DaisyCsound by following the instruction below:
https://github.com/csound/csound/tree/develop/Daisy/DaisyCsoundExamples

Finally I built daisyCsoundGenerative.bin and daisyCsoundMidi.bin, but how can I upload them to Daisy Seed?
I also found dsy_bootloader_v5_4.bin in the repository. I guess the default boot loader should be replaced by this, but no idea how to do it.

Any help would be greatly appreciated!

Best regards,

Hi,

I’m using MacOS to build DaisyCsound from copied repository.

Dear Aman,

Thank you for your explanation.
After running "make program-boot”, dsy_bootloader_v5_4.bin was successfully written into Daisy Seed (Error 74 can be ignored).
However, I got an error for “make program-dfu”. The complete error log is attached below.
It tried to write the program to the address 0x90040000(QSPI Flash), which is as expected because APP_TYPE = BOOT_QSPI is configured in the Makefile.
QSPI flash is 8MB and the bin file is 2.2MB, so the error should not due to lack of memory.
Any further help would be greatly appreciated!

Best regards,
Teteuya Miwa

Dear Aman,

Thank you very much for the detailed step-by-step instructions.
Finally I can successfully run Csound on Daisy Seed. This is wonderful!
One important point I can add to Step 3 is that I need to press the boot button after pressing reset button, and while the LED is blinking briefly.

Also you only need to flash the bootloader once, after that if you make any changes and want to flash an example again you can just follow steps 3 and 4 from above.
