Hi everyone,STM32MP1 ROM Code has default AF mux for SPI_NOR/NAND like this:QUADSPI_CLK -> PF10 (AF9)QUADSPI_BK1_NCS -> PB6 (AF10)QUADSPI_BK1_IO0 -> PF8 (AF10)QUADSPI_BK1_IO1 -> PF9 (AF10)I want to remap to the new pins using the OTP CFG5..7The poins...
My device tree configuration { spdif_out: spdif-out { #sound-dai-cells = <0>; compatible = "linux,spdif-dit"; status = "okay"; spdif_out_port: port { spdif_out_endpoint: endpoint { remo...
The debugger returns an error Failed to execute MI command target temote 3333
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...
