Imam LPC2387, ki ima vključen enega od CRP nivo varnosti.
Citiram: |
CRP1 disables access to chip via the JTAG and allows partial flash update (excluding
flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is
required and flash field updates are needed but all sectors can not be erased.
CRP2 disables access to chip via the JTAG and only allows full flash erase and update
using a reduced set of the ISP commands.
Running an application with level CRP3 selected fully disables any access to chip via the
JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too.
It is up to the user’s application to provide (if needed) flash update mechanism using IAP
calls or call reinvoke ISP command to enable flash update via UART0. |
Vendar obstaja možnost programiranja in ponovno vključitev jtag programiranja preko uarta. Ta postopek mi je že prej nekajkrat uspel. Problem pa je nastal zdaj, da mi tudi prek uarta programiranje ne deluje več. Kdo ve kako to rešiti?
Uporabljam pa flashmagic in h-jtag programator ter h-jtag server za programiranje. _________________ Moja delavnica ni razmetana, je samo taktično urejena. |
