<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">I would recheck that, because I have got incorrect results with the original setup which is in the fact what you propose. So I have switched to conservative <code style="font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; margin-top: 0; font-weight: inherit; overflow-wrap: break-word; white-space: break-spaces; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; word-break: keep-all; padding: 0.125rem 0.25rem;">enabled-by</code> individual BSPs and it worked for me.</p>

<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">should work, is that right?</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">I have tried such things and got incorrect results.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">Anyway, the TMS570 BSP needs some care before 7.0 release. Because changes by Airbus, you and others introduced 4357 but the options has been flipped which resulted in the Flash builds (probably these whee safety matters) to disable SRAM check and even ECC on it and parity check on peripherals. On the other hand in SRAM build the test code wiped out out itself by destructive internal SRAM tests.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">I have done some steps to make it work again but it needs this and probably some more changes. Problem is, that I have my older OpenOCD branch which flashes 3137, but my attempts to use my knowledge to make current OpenOCD attempts (based on other's code my and corrections) to wok with 4357 are not successful yet. But on the other hand I have colleagues with Ti tools on the computer at company where I provide consultations so I have some possibility to flash 4357 as well.</p>
<p dir="auto" style="color: #3a383f; margin: 0;" align="initial">I have spoken with Ti representatives at Embedded World this year and they have informed me that they have their public OpenOCD for which works with their newer chips. But they did not respond to my followup e/mail to provide documentation for TMS570 Flash and possibly source library blobs code... But I try again when I have some time.</p>
