hi everyoneI'm trying to search for a certain char array(say char Temp[]) within a lager array in this case, char Rcv[500]. here is my codeint scanRcv(char *Temp){ int ii=0; for(int i=0;i<RcvLength;i++){ while(Rcv[i]==Temp[ii]){ ii++; if(ii==strlen...
I want to know the memory size of STM32MP151CAA3 that Coprocessor(Cortex-M4) can use.https://wiki.st.com/stm32mpu/wiki/Boot_chains_overview#STM32MP15_boot_chainthis wiki page says that coprocessor(Cortex-M4) program loaded in MCUSRAM(384kB).Does this...
I'm bringing up a custom STM32MP15x-based design, and I'm encountering what looks like stack corruption issues in U-Boot (and I can't get a kernel to boot).Symptoms:I've enabled early debug printing, and get the following output:U-Boot SPL 2020.04-st...
I know that to get PPS output on the Ethernet PPS Pin PG8 that the device tree has to configure the pin for AF11. I also believe that PPS has to be enabled somehow? On some embedded Linux systems there is a /sys/class/ptp/ptp0/pps_enable variable to...
Hello,Our team is currently working on stm32mp1 boards (the dk2 and the ev1).Our software architecture is using TFA, OPTEE, Uboot and Linux.For our needs, we have developed an SPI driver for OPTEE. The OPTEE version on which we developed this driver ...
I changed name of orginal device-tree of my board stm32mp157c-dk2.dts. Then I tried upload tf-a and uboot to device via STM32_Programmer_CLI. Program proper uploaded tf-a and I see my new Model name but now program wait for reconnecting and my device...
We are searching for a training possiblity on the MP1 processor, which is in Germany. Mainly we are interested in the HW and the software e.g. multiprozessor handling. There are online courses but they do not deep dive. Anyone an idea about this? ST ...
Hi,I have a custom board with a ST32MP157C and a 24AA025E48 on a i2c bus.In the U-Boot, I want to read the MAC address located in the 24AA025E48 on the i2c bus 1 at address 0x53 at offset 0xFA.When I can use the following commands it works (MAC Addre...
HiI am working on the A7-M4 big data exchange example included in the next branch:https://github.com/STMicroelectronics/meta-st-stm32mpu-app-logicanalyserThere is a la_reserved node that is included in thereserved-memory node of the stm32mp157c-demo...
