LS1021A: Bypass RCW electrically

z_v — Sat, 17 Dec 2016 14:42:48 GMT

Hello,

In the TWR, SW-2\3 are used also to bypass the burned RCW.

How ? What bits in the RCW can be bypassed this way ?

Thank you,

Z.V

Sorry, in which document this is stated?

Hi Ufedor,

For example:

S3.5 : 0 - NOR bank 0

1 - NOR bank 1

How does S3.5 affects the source from where u-boot runs ?

Who reads the position of the switches ?

Thank you,

Z.V

S3.5 is connected to the CPLD which controls MSb of the NOR Flash address.
