Hello Karol,
yes, I think I could remember a screenshot in a former forum post, where ICKL was set to 192 MHz as well.
I'll trie to change the ICKL to 192 Mhz and PCBCLK to to 24MHz, but problem is still the same.
I'think I get a S1-DK in next days so I'll wait and test ist then again the complete sample with the corresponding HW.
I've tried to program your SREC file, but it doesn't work. Programming out of the box sample is no problem, but there always a bin file is used.
Thank you and best regards
Ralph
