Hi.
I'm currently porting NuttX to some proprietary compute modules with
STM32F7 and STM32H7. Each and every board has got a small AT24MAC402 256
Byte EEPROM with additional UID and MAC address accessible under a
second I2C address, and many boards have an additional AT24C256 32kB EEPROM.

There are several Microchip/Atmel boards that come with an Atmel MAC in
AT24MAC402 EEPROM. You should be able to clone that logic (including
setting the MAC address). See:

Hi.
I've created several board support packages, each in its own out-of-tree

Hi.
Has anybody written a driver for I2C(Slave) to 1Wire (Master)

I'm writing several drivers for my custom hardware. One is for a PCA9633

can be used with PCA9633 (4 outputs), PCA9634 (8 outputs), and PCA9635

Hi!
Some months ago a member of this mailing list submitted a CANFD driver

Hi.
I'm wondering where the driver for the STM32F7/H7 DACOUT pins is. For
STM32F7 I can select DACOUT1 and DACOUT2 in menuconfig, but I don't find
any accompanying source code. For STM32H7 I find traces of DAC
configuration, but work there seems to be still in progress.
For STM32F4 I do find

I have configured and installed Nuttx rtos on the Nucleo-H743zi2 board.
Now I want to create my own driver. How to create our own driver?
Has anyone created their own driver using Nuttx rtos on the STM32 board?
Could anybody please tell me how

Dear all,
has anybody implemented a LIN driver for SAME70 USART? The SAME70 USART
peripheral is capable of. A SW implementation (sllin.c - Pavel Pisa) would
also be interesting!
Would you extend sma_lowputc.c and sam_serial.c or would you grep USARTx

Hi;
there is a global shortage of STM32 processors on the market. I've seen
STM32F767 selling for 480U$.
Has anybody tried Gigadevice processors? They claim to be STM
replacements. I've got a design ready for a 144 pin STM32 (either F767
or F427/429), and it seems that the GD32F427 are repla
My thoughts: simple things should be simple. Getting temperature or
humidity values from a sensor only requires a few lines of code. A
simple character driver fells just right for me.
More code brings more potential bugs with it. The character drivers
should remain as an option for simple thin
all stm32 families (at
least the big ones).

Indeed the ICE fpgas are loaded by SPI. Interesting.
But mine is loaded by JTAG.
What FPGA type do you use EXACTLY?

Hi,
I'm currently in the process of testing all peripherials on my Nucleo

My next step would be CANFD, but I've noticed that there is no
