I am trying a simple CM33 ELF test. This one just has the STM32CubeMX boilerplate for the CM33 (non secure). I added a toggle on GPIOJ[6]. I stripped out a ton of the inits leaving just the GPIOJ[6] and pin toggle. after the seq below LED3 *does* tog...
Facing an issue with the boot* pins. As shipped, BOOT_LOCK==0, NBOOT_SEL == 1, NBOOT[1:0] = 2'b11. Using CubeProgrammer we set the option bytes to:BOOT_LOCK==0, NBOOT_SEL==0, NBOOT[1:0] = 2'b00When NBOOT_SEL == 1, the no external pin jumper setting, ...
Saw the summit last Tue, 10 stm32u073s arrived Fri from mouser, I had Ada working on it yest (sat). Some work to get the openocd cm0 assembly flash writer to work (l4 version's cm4f code -> cm0+). Ada was the usual porting effort. (I have done F103, ...
The doc and SVD file don't have a reg at offset 0x44 (GTZC_TZSC_MPCWM3BNSR).Since GTZC_TZSC_MPCWM3ANSR @0x40 exists, via symmetry I would expect B also at 0x44.The doc does say this:GTZC_TZSC external memory x non-secure watermark register 1(GTZC_TZS...
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?​T​n...
