Hi
Apologies in advance if these are daft questions, however I'm trying to put together a development kit for the SR5E1E5 .
I have found the SR5E1-EVBE5000P evaluation board, but need a debugger to use with it. I assume that the ST-LINK/V2 is compatible but can someone please confirm this? Also can the Stellar Studio All in One be used with this combination?
The SR5E1-EVBE5000P has a USB connector can I assume this does not support debugging via Stellar Studio All in One?
We already have the SPC5-UDESTK, but I assume that this is not compatible with the Stelar series of micros?
Thanks in advance.
Solved! Go to Solution.

Ah - I stand corrected!
Although the list of Development Tools has no mention of ST-Link - but Segger J-Link and IAR's I-Jet are in there:

PS:
I was thinking of The SPC5 family - which is a Power PC Architecture

Doesn't look like it.
See here : https://www.st.com/en/automotive-microcontrollers/sr5e1e5.html#tools-software
Section "Hardware development tools" only lists a "StellarLINK" which is flagged as "NRND".
Just saying.

I would suggest to check out the documentation, found here : https://www.st.com/en/evaluation-tools/sr5e1-evbe5000p.html#documentation
But the UM lists standard 10-pin and 20-pin debug headers, so you can use any compatible debug pod your preferred toolchaiin supports.

I think not.
The ST-Link is for STM32 (and STM8) - the Stellar MCUs are something completely* different.
* EDIT: Maybe not so different - see below ...

The description on ST's website says :
SR5 E1 line of Stellar electrification MCUs, 32-bit Arm Cortex-M7 automotive MCU 2x cores, 2 MB Flash, rich analog, high-resolution timer, HSM, ASIL-D
So, expecting ST's standard debug pod for Cortex Ms to work is not unreasonable.
I didn't go into details, but statements like "Split-lock configuration, allowing either 2 cores in parallel or 1 core in lockstep configuration" suggest it is more like a Cortex R.

From the first post I assumed a SPC5 board as well.
To be honest, I never heard of that family before either. Probably new products, superceeding the SPC5 devices.
"Lockstep" and "ASIL" are terms associated with software adhering to functional safety standards, historically covered by Cortex R devices.
My company gave up on "rolling their own" a few years ago, and instead went for conformant off-the-shelf ECUs.
And I notice a shift in these devices to more performant silicon as well, although often Aurix Tricore.

STLINK-V3 is firmware locked to STM32 devices. V2 firmware can talk to devices of other brands via JTAG/SWD. . ST stlink software probably not.

Not new as it seems.
From the datasheet it seems to be available since Apr 2022.. It has been available for four years already...
But I don't have any idea about that product.

I didn't catch that.
Although it doesn'ts surprise me. From the description, it sounds like a quite complex and expensive beast, for a special market niche. And probably not with a huge amount of sales.
My company is effectively part of the target audience, and we prefer it in a commercial ECU, packaged with proper RT-OS and libraries.
