ESP32 / ESP32-EVB Rev.F pins for two I...

Last post by GeorgeFlorian - November 01, 2024, 04:03:38 PM

Apart from GPIO13/I2C-SDA and GPIO16/I2C-SCL what other pins can be used for I2C ?
Does this board have 2 I2C Bus interfaces ?

I want to link up a LCD display and a sensor to the ESP32-EVB Rev.F and I don't even know if it's possible on this board.
I was led to believe that we can use any free GPIO as I2C.

Just look at the contributors at the u-boot-olinuxino and olinuxino-tools projects at the Olimage GitHub projects and contact them over GitHub, I can't promise they'd want to assist you, tho.

Unfortunately, that is all support I can provide for the software. Anything else would require considerable time and effort and this is open source project with all sources available even without purchase.

Hi,

I went through the stm32-ddr-1x4Gb-binG.dtsi file of the Olimax and I have generated my file from the cubeMX and there were certain parameter which are not present in the generated file such as -

#define DDR_DX0DLLCR 0x40000000
#define DDR_DX0DQTR 0xFFFFFFFF
#define DDR_DX0DQSTR 0x3DB02000
#define DDR_DX1DLLCR 0x40000000
#define DDR_DX1DQTR 0xFFFFFFFF
#define DDR_DX1DQSTR 0x3DB02000
#define DDR_DX2DLLCR 0x40000000
#define DDR_DX2DQTR 0xFFFFFFFF
#define DDR_DX2DQSTR 0x3DB02000
#define DDR_DX3DLLCR 0x40000000
#define DDR_DX3DQTR 0xFFFFFFFF
#define DDR_DX3DQSTR 0x3DB02000

can you please explain why are this used. and is this only parameters which are needed to be change or there are more parameters which are needed to be changed.

configs/STM32-OLinuXino-SOM_defconfig

Maybe also check arch/arm/dts/stm32mp1-olinuxino-som.dts and arch/arm/dts/stm32mp1-olinuxino-som-u-boot.dtsi

Also maybe look in the commits:

Thank you for your reply,

Can you please tell me the which deconfig file to use in the config directory to build the custom u-boot

The software is open source, all sources are available at our GitHub, you'd have to edit the u-boot for the different RAM settings. I can't do it for you. What exactly depends on the RAM but check this guide about links to sources and description of rebuilding:

I have designed the board and is planning to populated the board, can you please suggest if I am going to change the RAM on the board then what are the changes which are needed to be made in the software and where to make the changes and can you please suggest any reference from where I can get the idea.

A20 / how to get analog output to Li...

Last post by Unchip - October 28, 2024, 12:00:58 PM

Target is to use Lime2 as a "virtual temperature measurement" instead of real NTC to fool a heat pump. how to get analog output to Lime2 or other ideas how to make a virtual NTC?
