42 | Define this if you don't want to or can't have an environment stored | |
919d25c9 | 43 | on a storage medium. In this case the environment will still exist |
c1c3fe23 SG |
44 | while U-Boot is running, but once U-Boot exits it will not be |

104 | help |
105 | Define this if you have a flash device which you want to use for the | |
106 | environment. | |
107 | ||
108 | a) The environment occupies one whole flash sector, which is | |
109 | "embedded" in the text segment with the U-Boot code. This | |
110 | happens usually with "bottom boot sector" or "top boot | |
111 | sector" type flash chips, which have several smaller | |
112 | sectors at the start or the end. For instance, such a | |
113 | layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In | |
114 | such a case you would place the environment in one of the | |
115 | 4 kB sectors - with U-Boot code before and after it. With | |
116 | "top boot sector" type flash chips, you would put the | |
117 | environment in one of the last sectors, leaving a gap | |
118 | between U-Boot and the environment. | |
119 | ||
120 | CONFIG_ENV_OFFSET: | |
121 | ||
122 | Offset of environment data (variable area) to the | |
123 | beginning of flash memory; for instance, with bottom boot | |
124 | type flash chips the second sector can be used: the offset | |
125 | for this sector is given here. | |
126 | ||
127 | CONFIG_ENV_OFFSET is used relative to CONFIG_SYS_FLASH_BASE. | |
128 | ||
129 | CONFIG_ENV_ADDR: | |
130 | ||
131 | This is just another way to specify the start address of | |
132 | the flash sector containing the environment (instead of | |
133 | CONFIG_ENV_OFFSET). | |
134 | ||
135 | CONFIG_ENV_SECT_SIZE: | |
136 | ||
137 | Size of the sector containing the environment. | |
138 | ||
139 | ||
140 | b) Sometimes flash chips have few, equal sized, BIG sectors. | |
141 | In such a case you don't want to spend a whole sector for | |
142 | the environment. | |
143 | ||
144 | CONFIG_ENV_SIZE: | |
145 | ||
146 | If you use this in combination with CONFIG_ENV_IS_IN_FLASH | |
147 | and CONFIG_ENV_SECT_SIZE, you can specify to use only a part | |
148 | of this flash sector for the environment. This saves | |
149 | memory for the RAM copy of the environment. | |
150 | ||
151 | It may also save flash memory if you decide to use this | |
152 | when your environment is "embedded" within U-Boot code, | |
153 | since then the remainder of the flash sector could be used | |
154 | for U-Boot code. It should be pointed out that this is | |
155 | STRONGLY DISCOURAGED from a robustness point of view: | |
156 | updating the environment in flash makes it always | |
157 | necessary to erase the WHOLE sector. If something goes | |
158 | wrong before the contents has been restored from a copy in | |
159 | RAM, your target system will be dead. | |
160 | ||
161 | CONFIG_ENV_ADDR_REDUND | |
0649cd0d SG |
162 | |
163 | These settings describe a second storage area used to hold | |
164 | a redundant copy of the environment data, so that there is | |
165 | a valid backup copy in case there is a power failure during | |
166 | a "saveenv" operation. | |
167 | ||
168 | BE CAREFUL! Any changes to the flash layout, and some changes to the | |
169 | source code will make it necessary to adapt <board>/u-boot.lds* | |
170 | accordingly! | |

182 | environment. | |
183 | ||
184 | CONFIG_SYS_MMC_ENV_DEV: | |
185 | ||
186 | Specifies which MMC device the environment is stored in. | |
187 | ||
188 | CONFIG_SYS_MMC_ENV_PART (optional): | |
189 | ||
190 | Specifies which MMC partition the environment is stored in. If not | |
191 | set, defaults to partition 0, the user area. Common values might be | |
192 | 1 (first MMC boot partition), 2 (second MMC boot partition). | |
193 | ||
194 | CONFIG_ENV_OFFSET: | |
195 | CONFIG_ENV_SIZE: | |
196 | ||
197 | These two #defines specify the offset and size of the environment | |
198 | area within the specified MMC device. | |
199 | ||
200 | If offset is positive (the usual case), it is treated as relative to | |
201 | the start of the MMC partition. If offset is negative, it is treated | |
202 | as relative to the end of the MMC partition. This can be useful if | |
203 | your board may be fitted with different MMC devices, which have | |
204 | different sizes for the MMC partitions, and you always want the | |
205 | environment placed at the very end of the partition, to leave the | |
206 | maximum possible space before it, to store other data. | |
207 | ||
208 | These two values are in units of bytes, but must be aligned to an | |
209 | MMC sector boundary. | |
210 | ||
211 | CONFIG_ENV_OFFSET_REDUND (optional): | |
212 | ||
213 | Specifies a second storage area, of CONFIG_ENV_SIZE size, used to | |
214 | hold a redundant copy of the environment data. This provides a | |
215 | valid backup copy in case the other copy is corrupted, e.g. due | |
216 | to a power failure during a "saveenv" operation. | |
217 | ||
218 | This value may also be positive or negative; this is handled in the | |
219 | same way as CONFIG_ENV_OFFSET. | |
220 | ||
d11d1bec MV |
221 | In case CONFIG_SYS_MMC_ENV_PART is 1 (i.e. environment in eMMC boot |
222 | partition) then setting CONFIG_ENV_OFFSET_REDUND to the same value | |
223 | as CONFIG_ENV_OFFSET makes use of the second eMMC boot partition for | |
224 | the redundant environment copy. | |

254 | can be written. This should be a multiple of the NAND device's | |
255 | block size. Specifying a range with more erase blocks than | |
256 | are needed to hold CONFIG_ENV_SIZE allows bad blocks within | |
