hello, some updates:
changed FRAM, still no go.
I connected Olimex Jtag (with imx28.cpu config) , and this is the result:
adapter speed: 6000 kHz
dcc downloads are enabled
Warn : JTAG tap: imx28.cpu UNEXPECTED: 0x227e40cb (mfg: 0x065 (Analog Devices), part: 0x27e4, ver: 0x2)
Error: JTAG tap: imx28.cpu expected 1 of 1: 0x079264f3 (mfg: 0x279 (SigmaTel), part: 0x7926, ver: 0x0)
Error: Trying to use configured scan chain anyway...
Error: IR capture error at bit 4, saw 0x21 not 0x...3
Warn : Bypassing JTAG setup events due to errors
Error: unknown EmbeddedICE version (comms ctrl: 0x00000000)
The fact it seems not to recognise the CPU, it means that the DSA stops at what stage ?
