thanks richard

made me go back and have a look at the files in 5.40 mplab , there is no /mpasmx directory , and i checked this 2 times by re downloading ver 5.40 being the latest version
i made the error or removing prev versions of mplab because of updating to the latest version

so now have reinstalled 5.35 , which is last version and has /mpasmx directory , and has mpasm.exe ver 5.87 , which appears to be the last version available from now on ???
after adding it to the tool chain , mplab complains that the mpasm is not supported in 64 bit systems and to migrate the project or use earlier ide

its seems microchip use of mpasmx for the 8bit chips is to be dropped


This appears to now assemble the tinybootloader file

still like to know where dave found those files as i cant find them on the source download

see if the pc software see it after its loaded
