Hi everyone,I'm trying to optimize the boot time of tf-a with Yocto but don't find much information on the web. Currently tf-a takes about 1s from the point in which it is read from NOR to the point it loads UBoot from same NOR. I optimized the Linux...

Hi community,I'm facing problems to upload the flash layout on a custom board with the STM32CubeProgrammer. I tried with the last version (v2.10.0) but also older ones. The USB communication seems to be working fine as there are not checksum errors o...

Here the relevant parts of my device trees:******************TF-A*******************&pinctrl { rcc_pins_mx: rcc_mx-0 { pins { pinmux = <STM32_PINMUX('G', 2, AF1)>; /* RCC_MCO_2 */ bias-disable; drive-push-pull; slew-rate = <2>; }; };...

Hi @Community member,Thank you very much for your help. I tried setting different EXTRA_OEMAKE flags following 2 approaches:Using the TF-A Makefile Flags as described in my commit of the repoUsing the flags that STM suggestsBut the only 2 EXTRA_OEMA...

Hi @Kevin HUBER ,Thanks for your answer. It is good to know that the problem has been already tackled.I applied the corresponding UBoot patches but the problem in Linux persists as described above. Are you shure the Linux (5.10.61) driver can deal w...

Hi @Community member ,Thanks for your response. In the CubeMX I set both ports to the same COM10 and the SPL gets loaded but then there is no communication.The command you suggest can load and start the SPL successfully:STM32_Programmer_CLI.exe -c p...

Hi @PatrickF ,I was trying to test the RAM-related timing margings of our board with the procedure you shared:https://drive.google.com/file/d/1Dh6jFb2rsjWcGXMupsuK4UVD33Y6OnmP/viewHowever I'm having some problems to get the SPL with DDR_INTERACTIVE ...

Hi @PatrickF ,We have tried a couple of things you suggested and I would like to update about the partial results:I'm using TF-A out-of-the-box (no own recipe nor own defconfig). And in the machine config I set both CUBEMX_DTB_PATH_TFA and CUBEMX_DT...
