Looks like we have a basic idea of how to set it up. Readme has misc issues (bad steps, unclear order, etc)
Current state of project from what I can tell 1) Firmware extraction: WCH bootloader, T48 bootloader, and T48 main firmware are dumped 2) Firmware update via bootloader: we know a...
Recent code refactoring changed the printing and parsing of the ZIF state as part of a larger PR. Unfortunately it seems to no longer parse correctly Proposal: change back to...
Need this for two things: - Fix bricked devices - Workaround until bootloader is understood I think the furthest anyone has gotten so far: they played with blackmagic branch that...
We probably have enough info to do this already but we don't have the bootloader itself to study. This is needed, for example, to understand recovery mechanisms for bad firmware....
Full schematic is WIP. However I think we have enough info to make this work? "That LED is on pin 16 of the CH32V307 AFAICT PC1"
A few times we've observed what looks like some sort of reliability issue. Ex: yesterday tried to set VPP and it wasn't working. Re-init device and starts working again. Think...
bitbang seems stable enough that users shouldn't have to compile from source
Reference here: http://www.itisravenna.it/sheet/anm033.pdf A number of mcs51 mask ROM parts of interest have come up recently. Looks like this could be implemented directly on the TL866 without a PCB, but...
