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:
- The main processor sends the Get Storage Info command. The user must provide the storage ID for the SRAM.
- The CC3120 or CC3220 device responds with an Ack followed by the Storage Info response. The response includes the block size and number of blocks for the SRAM.
- The main processor responds with an Ack.
Figure 7 shows the Get Storage Info command followed by an Ack and Storage Info Response.
