sigrok wont work with my LA hardware but I used their Pulseview software to decode a csv-export from the 'Labtool' software with the Pulseview included parallel decoder.
I captured A0-A9 plus the uC RST pin, ADC still out of circuit.
Decoded A0-A9, only to find that an error is reported 2 cycles after A8 goes high. Since it's all 8-bits I reverted to decoding A0-A7 and no error messages. Why capture A8 and A9 (other than seeing it is not entirely dead)?
I tried several methods of capturing a reset and by the looks of it managed several times (out of 30 or so...) but the hex dumps were all different from each other and none contained 02 02 8B, not even 02 02.
Let's consider the two possible outcomes of this exercise:
1. it jumps to the code in EEPROM but still I dont get the required ICV-signal
2. it doesnt jump to the code in EEPROM and that's why I don't get the required ICV-signal and keeps resetting.
In case 1. I would replace EEPROM?
In case 2. I would replace uC?
