Unable to specify partition size when using nvs_partition_generator

[dermondbaer]

Hello,

I'm trying to create a custom I/O mapping but am stuck with the nvs_partition_gen.py script rejecting the size parameter. I'm using the latest script from espressif and am able to create a binary partition, although it's only 4KB (exactly 4096 Bytes) in size and the ESP won't boot after flashing it.

I noticed you have changed the aforementioned parameter a few times recently, so I thought you could maybe shed some light on this issue.

Although I guess it won't be of use I'll paste my configuration here, just in case: custom.txt

Yes, the tool was unstable. $ ./nvs_partition_generator.sh custom.csv python C:/msys32/home/jp/esp/esp-idf/components/nvs_flash/nvs_partition_generator/nvs_partition_gen.py custom.csv build/custom.bin 8 done

custom.zip

Thanks for the .zip - the tool is still not working for me (Ubuntu 18), but I'm using a HEX editor to fill up the last 4096 Bytes with FF's, so for me that's not a problem anymore.

This is out of context, but I'd rather not open a new issue just for this: I'm not able to get my ILI9341 Display (MI0283QT-9A) to work although I'm pretty confident I wired and powered everything as needed - of course I'm using a different configuration from the above (standard_adb.bin). I saw the last commit (1.5 R1) states "lcdout was not working". Should it work with the new revision or could it still be a software issue? I guess you probably don't have a ILI9341 display to try it out? I wired everything except from the A0 pin, which in my understanding isn't needed.

Thank you for your efforts, you've created an impressive project!

Bad idea. May be it's time to update esp-idf

I own many ILI9341 fully tested in all configurations. A0 is mandatory. Please read https://github.com/karawin/Ka-Radio32/blob/master/HardwareConfig.md A0 is P_LCD_A0 or default to PIN_LCD_A0 GPIO_NUM_14

lcdout was not working : lcdout is a simple tempo to clear the lcd when no new event to display.

Indeed I used an old version of the esp-idf, when cloning the repository I didn't notice the -b v3.1.1 option in the documentation: git clone -b v3.1.1 --recursive https://github.com/espressif/esp-idf.git

One more question regarding the LCD though: In this datasheet, page 10 and 11, can you tell me at first glance which pin connects to A0 and which one to SCL (supposedly 36 and 37)? And the interface mode is 4-wire 8-bit data serial interface II? I've tried both ways, but the screen stays white all the time.

Otherwise I'll just keep trying, I don't want to waste your time.

My 2.4 TFT SPI 240x320 pins:

bottom to top VCC 3.3 GND CS is PIN_LCD_CS GPIO_NUM_13 //CS RESET PIN_LCD_RST GPIO_NUM_2 //Reset RES RST or not used DC PIN_LCD_A0 GPIO_NUM_14 //A0 or D/C SDI(MOSI) PIN_NUM_MOSI GPIO_NUM_23 // Master Output, Slave Input Named Data or SDA or D1 for oled SCK PIN_NUM_CLK GPIO_NUM_18 // Master clock Named SCL or SCK or D0 for oled LED to 3.3 with or without a resistor

All the other pins are clear to me, it's just the A0 zero pin that I can't assign to one on the lcd - I thought it's possible you have the same model.

Probably I'll try to get another display - can you recommend a bigger one, maybe around 2 or 3 inches in size? I'm only seeing the small OLED displays (0.91", 1.3", ...) that are widely available on ebay etc.

A0 also named DC or D/C is used to switch from command data to pure data on MOSI

2.8'' is the biggest resolution 240x320 adapted for the software. May be a future evolution.
