#103423 - the debug/programming is nonstandard so Responding to: ???'s previous message |
Hi everyone, is there anything like 'universal JTAG programmer/debugger' for MCS51 devices which support JTAG? Or the JTAG communication protocol vaires with different manufacturer? Is the hardware same and do we need different software for different manufacturers?
JTAG has never been "intended" for programming/debugging, thus the debug/programming is nonstandard and the likelyhood that multiple manufacturers hav implemented it the same way is very small. The hardware should be, at least, very similar, since all I know allow JTAG chaining which would be impossible with nomnstandard signal path. BTW you mention 'universal' which '51 chips but SILabs have JTAG ? Erik |

| that would be silly from SiLabs | 01/01/70 00:00 | |
| HUH? | 01/01/70 00:00 | |
