Upgrading spresense board flash memory
-
I used the recovery tool last week and it worked for me.
Can you describe what happened? -
@maxieaussie-0
Let me investigate this about the commands that are used by the flasher and get back to you. -

Can you describe what happened?the incrementing dots just stopped a some point (after pressing those buttons in the correct sequence/way). It seems that I now have a "bricked" spresense board lol (I have 2 other ones though).
-
@CamilaSouza I attached below the content of the boards.txt file found in
C:\Users<myusername>\AppData\Local\Arduino15\packages\SPRESENSE\hardware\spresense\2.6.0
(again I am not really familiar with Arduino, usually just use "normal" embedded programming ).
line 48-59 are most likely that gives the options of "Memory size" in the IDE (it corresponds to those).If you scroll down further to line 61-85 these seems to specify the flash size and RAM size
The question remains is that why the maximum Flash size specified (1536 KB/ 1572864-I think they have taken in to account bootloader size, etc) seems to be the same as RAM size?
I am assuming Flash size is specified by "upload.maximum_size" and RAM is specified by "upload.maximum_data_size"- by looking at other "boards.txt" from other Arduino boards
(UNO Mini, Leonardo, Micro, Nano)Perhaps Sony team who wrote spresense board definition could shed some light?

Hm... You're the second user to report this issue. But I haven't been able to reproduce it.
Let me ask you, what is the operating system you used with the recovery tool? -
@maxieaussie-0
I am not with the Sony team but I can point you to the fact that the Spresense bootloader takes the uploaded binary, copies it to RAM and executes the code from RAM. The Flash is connected via a system MCU. You cannot access flash directly from the application cores. There is no code execution from Flash memory. All your code ends up in the RAM effectively reducing the memory for stack & heap memory. So the maximum for your Arduino application is in fact 1536KB.
See the line below. The setting is used to configure how much memory you will reserve for the sub cores. Second usage is the check if your program fits into memory.-Wl,--defsym,__reserved_ramsize=1572864-{upload.maximum_size}May I ask what is the reason for the QSPI Flash upgrade?

@jens6151-0-1-1 Hi Jens. Ouch! Thanks for clarifying this. I was hoping to store my tflite model which is not so lite :-)-tried all conversion options with no luck . Converted to const it ended up around 56,172,546
I think I might have to change to a Renesas RZ/V2L MCUs! (I am not into Coral Boards and alikes). I was only using Arduino for a quick check but yes even with any other option there is no way the model would fit! -
Exactly, @jens6151-0-1-1
Thanks for the answer. -

You do not have XIP so in practice the maximum model size is much less than 8MiB, and that needs to be fixed on the edge impulse site otherwise people will try to use large models.

I see your point.
We are always trying to improve our documentation and all feedback is valuable.
I'll share your feedback with the responsible parties.
