Firmware: Fix embedded SRAM test results storage method

[andrempmattos]

Create the implementation following this example storage procedure:

Cycle 1:
Store header_1
Store payloads_1
(pointer_unread_addr->header_1, pointer_unread_length->[size_of(header_1+payload_1)]

Cycle 2:
Store header_2
Store payloads_2
(pointer_unread_addr->header_1, pointer_unread_length->[size_of(header_1+payload_1)]

Cycle 3:
Store header_3
Store payloads_3
Read header_1
Read payloads_1
(pointer_unread_addr->header_2, pointer_unread_length->[size_of(header_2+payload_2)]

Cycle n: (end addr)
Store header_n
Store payloads_n

Cycle n+1: (overflow handler recycle the memory)
Store header_1
Store payloads_1

...

Note: Pointers are used for size fixed blocks and set the useful block length

This approach is too complicated... I should invest in a simpler method
