Hey guys...
I have been playing around with a 2148 and olimex interface, as the description says, for a little while now.
The other day I was programming, had just set some PLL parameters and some time later when debugging the code, the chip seemed to stop processing.... When trying to reload the code to flash, several error messages appeared... I disconnected the chip from the interface and tried again... only to receive the following errors...(i am using openOCD and eclipse)
if i try to halt via telnet i receive the following:

When trying to reload the code to flash, several error messages appeared... I disconnected the chip from the interface and tried again... only to receive the following errors...(i am using openOCD and eclipse)
Code: Select all
However it still seems to connect to the chip... but i cannot seem to halt the cpu to load/erase the flash or perform any other tasks..Info : clock speed 1500 kHz
Error: JTAG scan chain interrogation failed: all zeroes
Error: Check JTAG interface, timings, target power, etc.
Error: Trying to use configured scan chain anyway...
Error: lpc2148.cpu: IR capture error; saw 0x00 not 0x01
Warn : Bypassing JTAG setup events due to errors
Info : Embedded ICE version 0
Error: unknown EmbeddedICE version (comms ctrl: 0x00000000)
Info : lpc2148.cpu: hardware has 2 breakpoint/watchpoint units
if i try to halt via telnet i receive the following:
Code: Select all
and "scan_chain" returns this
Info : Halt timed out, wake up GDB.
Error: timed out while waiting for target halted
in procedure 'halt'
Code: Select all
Does anybody have any ideas of what may be happening?? Many thanks in advance, but this is killing me!!! TapName Enabled IdCode Expected IrLen IrCap IrMask
