I try to build a secure solution based on Arm-v8m TrustZone feature by leveraging Ali TEE Air. However, the results after google are only for ck802t and Nuvoton M2351.Could anyone please provide an Ali TEE Air port guide for STM32L5xxx boards? Especi...
Hi,I have a NUCLEO L552 and I would like to run a very simple program (just blinking a led).I have placed my vector table @ 0x08040000 as described by the data sheet. to program the flash I use the J-Link from Segger. What is strange, is that I canno...
The sample code uses p256v1 (which seems to actually be p256r1). This curve works well.I Got PKA to sign correctly using p256k1 with some minor curve updates.I am having trouble setting up p224r1. Has anyone got curves other that p256 to work?Tn...
Hi. I want to use the OctoSPI to configure Xilinx FPGAs (e.g., Kintex-7) in the SelectMAP mode. Therefore I need 8 data bits, a chip select (CSn), a RD/nWR signal and a CLK to the FPGA. I know the OctoSPI is usually used for reading and writing to Q...
Hello. I was searching for information but I was unable to find clear answer. What is correct way to handle AT messages from gsm/bluetooth/gps modules ?I am making one product that will use at least two uart interfaces (SARA-R12) and NINA-W151 module...
I've been using the example AN4657 and following it to a T. I'm using the example project library files form the STM32L476G IAP_Main and modified them where necessary to work with the 552.I can successfully connect to TeraTerm via usart3 connection a...
Hello, I trying to test Demostration Firmware(*1) for my STM32L552E-EV evaluation Board, and in the documentation for this Demo is written:<<This demonstration has been tested with STM32L552E-EV (MB1372-C02) evaluation board and can be easily tailo...
I ported openocd to the stm32l522. https://github.com/morbos/openocd-0.10.1openocd -f board/st_nucleo_l522.cfgFrom there you can remote connect from gdb, flash, and see the s/ns processor regs. Watchpoints work also.Hedley
Reading this cell: 0xe0040000 will hard crash the CPU. You can do it from non secure code also, which opens the way for a possible denial of service attack.In gdb:x/x 0xe0040000I realize parallel trace (the tpiu reg in Q) is not implemented but...
