I've been happily coding along w JM60 (CQH in my case) firmware 4.0. Then I built a board with the MCF52211, that was my mistake. Legacy Codewarrior reports v4.0 firmware as stale. So, I built and installed v4.3 (using Legacy Codewarrior 6.3) which made Codewarrior 7.2 happy. Lots of errors testing the board with the diagnostics, but that's not the issue here. My problem is that firmware 4.3 broke my ability to work with CFv1 targets. Debugger reports "Cannot read memory". Using tryUSBDM utility I find that if I attempt to read more than 0xC0 bytes using a RBLOCK command I get a USB_TRANSFER_ERROR. (specifically RBLOCK 800000 C0 succeeds, RBLOCK 800000 C4 fails). Am I alone with this problem?
