I’ve notice that the hi-speed ADC example no longer worked, hanging on the line that enables the first 32k of SRAM.
I’ve just run this test code and and determined that enabling anything over 128k is still fine, but anything below that will cause the code to hang, with no errors given. Maybe there’s just a fault with my Redboard, but I thought I’d pass it on.
/*Artemis Redboard SRAM enable test.
'AM_HAL_PWRCTRL_MEM_SRAM_32K_DTCM' used to work, but now the program just hangs.
No errors at compile time and none reported via the serial port.
The final print statement doesn't happen.
AM_HAL_PWRCTRL_MEM_SRAM_128K and higher however do still work.

void setup() {
Serial.begin(115200);
Serial.println("Enable SRAM");
Serial.flush();
