According to the reference manual, this is the sequence to disable CPC for T1040/T2080:

 

# a. Clear all bits in CPCPAR0-CPCPAR15 to prevent new transactions from allocating in the CPC

# b. Set CPCCSR0[CPCFL]

# c. Wait for CPCCSR0[CPCFL] to be cleared by hardware

# d. Clear CPCCSR0[CPCE]

 

in u-boot, I did this:

 

mw 0xfe010208 0x0; sleep 1; mw 0xfe010000 0xc0000800; sleep 5; mw 0xfe010000 0x0; sleep 1

 

is that correct?

 

Thanks!
