5.3.4 Step 4: Get SRAM Storage Info

To introduce some fixes to the ROM bootloader, it is necessary to download patches to the SRAM. The procedure for getting information of SRAM storage follows:

  1. The main processor sends the Get Storage Info command. The user must provide the storage ID for the SRAM.
  2. The CC3100 or CC3200 device responds with an Ack followed by the Storage Info response. The response includes the block size and number of blocks for the SRAM.
  3. The main processor responds with an Ack.

Figure 5-6 shows the Get Storage Info command followed by an Ack and Storage Info Response.
