Hi,

Hi, I was able to compile the wallet (daemon - denariusd) I had to use makefile.arm instead of makefile.unix.  However, another problem arose - the wallet does not sync. I am trying to download the last chaindata from https://pos.watch/chaindata.zip but after start denariusd it do not get new blocks but stay at 2667869 Instead there are errors:

ProcessMessages(ping, 8 bytes) : Exception 'CDataStream::read() : end of data: iostream error' caught, normally caused by a message being shorter than its stated length
ProcessMessage(ping, 8 bytes) FAILED
ERROR: CheckProofOfStake() : INFO: read txPrev failed

ERROR: FetchInputs() : 225ef5b75d mempool Tx prev not found 3de53cd669

and many ORPHANs:

Try compiling latest v3.3.9.7 branch. Syncing from block 0 might be fast enough where it will take a day or 2 on ARM now. Otherwise I found using chaindata and restarting the wallet a few times to get past the orphans works.

Unfortunately nothing helps. When using chaindata I've restarted the daemon a dozen times and it didn't help. When I tried to sync from the beginning on v3.3.9.7 it always stops on block 1429. Please see attached screen.

Try using the chaindata from https://denarii.cloud (There is one specifically for ARM powered devices) you extract that into your Denarius data directory (usually ~/.denarius/ on Linux if not using Snapcraft)
