A fatal error occurred: Failed to write to target RAM (result was 01070000: Operation timed out) the fatal error I also get when trying to flash/erase/ etc. i have some esp32 that have usb, some don’t, some can flash, some need sounding g0, etc, I can mostly work with them, it’s only the latest batch, which ’seem’ to have this CH9102f that fail to flash with the above ‘A fatal error …’ BTW, regular connect via usb works, so i get console messages ok. thanks, danny [-- Attachment #2 --] <html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;" class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On 14 Sep 2022, at 18:14, CeDeROM <<a href="mailto:cederom@tlen.pl" class="">cederom@tlen.pl</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="">On Wed, Sep 14, 2022 at 3:43 PM Daniel Braniss wrote:<br class=""><blockquote type="cite" class="">Hi,<br class="">is there/will there be any support for this chip?
