[Csnd] DaisyCsound bootloader and flashing program

The Csound Mailinglist
1

Hello,

I’m trying DaisyCsound by following the instruction below:

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!

Hi,

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

Hi Tetsuya,

You should be able to flash the two examples like any Daisy program that uses the bootloader as per this:
https://daisy.audio/tutorials/_a7_Getting-Started-Daisy-Bootloader/

The dsy_bootloader_v5_4.bin will automatically be used (the makefile handles this).

So you can run:
make program-boot

and then:
make program-dfu

Make sure you have the Daisy toolchain installed and you can refer to the link above for the sequence of pressing the boot and reset buttons on the Daisy to enable it to be flashed.

Hope this helps!
Thank you,
Aman Jagwani

Hi!

I can confirm I got the Genarative example up and running on Daisy, then dis not have time to investigate it further…

It is exciting though!

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 0x90040000QSPI 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

Hi Tetsuya,

That error is occurring because after you flash the bootloader, you do not need to enter the Daisy into boot mode again. Here is the full sequence of flashing the bootloader and then the example binary:

  1. Enter boot mode - press and hold boot, press and hold reset, let go of reset, and let go of boot.
  2. run make program-boot
  3. press and let go reset and then press and let go boot - after this you should see the LED on the daisy gradually glow and fade repeatedly, indicating that the bootloader is ready.
  4. run make program-dfu

This sequence will ensure that the bootloader is flashed and then the example program is flashed to the correct memory location (QSPI) with the bootloader. 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.

Thank you,
Aman Jagwani

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.
