Hi guys, FYI:
Turns out I the problem resulted in the fact that during sleep - even though none of the peripheral's clocks are turned off - the GPDMA cannot access the internal SRAM (only the AHB RAM), and that's where the problem was. Maybe I'll save some trouble for someone. Turning the chips debug peripheral on probably disabled this limitation, but I could not find out which registers are written by openocd on connect, I could find no matches for the "mww" and "mdw" strings from the output other than the commands being registered.
