Another flash size question #511

Closed enelson1001 closed 7 months ago

enelson1001 commented 7 months ago

When I flash my M5Stack I get the following output.

ed@ed-ideacentre-AIO-910-27ISH:~/esp-rust-projects/m5stack/rust-lvgl-hello$ cargo espflash flash --monitor

After the MAC address: 3c:61:05:0b:e3:fc it shows App/part. size: 755,776/1,048,576 bytes, 72.08%

What is this line telling me?

I'm confused because it also says I have Flash size: 16M

partition size =/= flash size. The same as on your computers hdd. For more info look here

enelson1001 commented 7 months ago

Sorry about addition questions.

  1. It looks like it is using the default partition. Is that correct? 
    # ESP-IDF Partition Table
# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  0x6000,
phy_init, data, phy,     0xf000,  0x1000,
factory,  app,  factory, 0x10000, 1M,
  2. So is it telling me that the factory/app partition size is 1M and the program is taking up 755, 766 bytes or 72.08% of that partition. Correct?
  3. So how much should I increase the factory/ app partition size?
  4. How do I do that? Is there some config file I need to add to my rust project?
Vollbrecht commented 7 months ago

you can use whatever you want from your flash to be used. There is a command in espflash flash --flash-size=16MB that you can use to get the correct size calculated, as espflash doesn't know what type of flash is build onto your board. espflash assumes a default partition table if you don't give it one explicitly

enelson1001 commented 7 months ago

Thank you

enelson1001 commented 7 months ago

When I added the flash-size to the commend line it still reports App/part size the same as before.

Is this a bug?

Vollbrecht commented 7 months ago

no, just telling it that you are having a larger flash-size doesn't change the fact that it is using the default-partition table.

enelson1001 commented 7 months ago

For those people looking for answers. I created a folder under my project called partition-table and created a file partitions.csv.

My partitions.csv flie contents

# http://esp-idf.readthedocs.io/en/latest/api-guides/partition-tables.html
# This file uses a 3M factory instead of the default 1M

# The size 528k isn't arbitrary - it is the minumim size when
# wear leveling sector size is 4k
app_storage,  data, fat,     ,        528k

And then the espflash command

$ cargo espflash flash --partition-table=partition-table/partitions.csv --monitor

Produces the following

Chip type:         esp32 (revision 3)
Crystal frequency: 40MHz
Flash size:        16M

[00:00:00] [========================================]       1/1       segment 0x8000                                                                                       
[00:00:45] [========================================]     420/420     segment 0x10000

Which shows I have a app/part of 3M
