#3334 Finaly came around to test more of the board. It seems to work so we didn't receive a fake chip \o/

Hooked my trusty old buspirate to it and the bootloader talked to me <3:

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,7)

load 0x40100000, len 24236, room 16
tail 12
chksum 0xb7
ho 0 tail 12 room 4
load 0x3ffe8000, len 3008, room 12
tail 4
chksum 0x2c
load 0x3ffe8bc0, len 4816, room 4
tail 12
chksum 0x46
csum 0x46



If someone else uses a buspirate to monitor the bootloader, here are the commands:

Code: Select allHiZ>m 3
